The internet is great. It facilitates access to essentially all of the accumulated knowledge on Earth. The open source architecture of the internet allows anyone to create content, which for the most part is in the public interest. However, as most people are aware, there is content on the web which is created either for malicious intent (ie. to sell you something), or simply out of plain old ignorance. This brief blog aims at dispelling a certain myth perpetuated by both of those latter circumstances.. That myth is: Transmission lines cause, among other ailments, cancer and neurological disorders.. Transmission lines are so commonplace that most people are simply immune to their presence within their field of vision. However, when you are purchasing a house, they stick out like a sore thumb. Other than the obvious aesthetic drawbacks to a large transmission line neighboring your backyard, there is a worry about the negative health effects which accompany them.. The debate around the harmfulness ...

MIT researchers have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. It could lead to miniaturized, battery-powered devices for medical and materials imaging, contraband detection, and even geological exploration.. Magnetic-field detectors, or magnetometers, are already used for all those applications. But existing technologies have drawbacks: Some rely on gas-filled chambers; others work only in narrow frequency bands, limiting their utility.. Synthetic diamonds with nitrogen vacancies (NVs) - defects that are extremely sensitive to magnetic fields - have long held promise as the basis for efficient, portable magnetometers. A diamond chip about one-twentieth the size of a thumbnail could contain trillions of nitrogen vacancies, each capable of performing its own magnetic-field measurement.. The problem has been aggregating all those measurements. Probing a nitrogen vacancy requires zapping it with laser light, which it ...
In this issue of EPIDEMIOLOGY, Elliott et al1 report results from a large-scale UK case-control study on power lines and risk of cancer in adults-concluding that their findings should help to settle a long-standing debate on the safety of residential exposures to extremely-low-frequency magnetic fields from high-voltage overhead power lines and adult cancers.1 Strengths include the large sample of ,50,000 cases and ~80,000 controls as well as the register-based approach with excellent source data for estimating distance of residences to nearby power lines and the extremely-low-frequency magnetic fields around those power lines. Limitations, well discussed by the authors, include omission of exposure sources other than high-voltage power lines and lack of migration information.. The major limitation, however, seems to be the rationale behind this particular study design. Using some types of cancers as cases and other types as controls, in a situation of weak evidence of any risk for any cancer, ...
Classifying all market-participating devices in one of these categories simplifies development of the semantic framework. Such a framework provides context for energy market interactions and the concepts within these interactions. It also helps ensure that all devices are equal in a market, and regardless of wired or wireless communications preference, can participate as defined by their owners. The projected benefits are ambitious: to give consumers maximum choice in device decisions; prevent vendor lock-ins; and create an eBay-like energy market. There are benefits for utilities in these pilots too in the forms of reduced grid loads, reduced need for more transmission line investments, and support for virtual power plants (VPPs).. These benefits are not fully appreciated yet in the USA. But the challenges facing construction of high voltage transmission lines (NIMBY, costs, logistics, and project timelines) reduce the odds that large and remote generation will continue to be the only ...

Optimizations of these elements are required to overcome these challenges and to perform a variety of MR applications. In this study, two different microstrip designs with varying impedance lines along the length of the coil-one producing peak magnetic field in the center and the other extending the length of usable magnetic field along the length ...
Heavy ice coating of overhead transmission lines created the serious threat on the safe operation of power grid. The measurement of conductor icing had been an effective and reliable methods to prevent potential risks, such as conductor breakage, insulator flashover and tower collapse. Because of the advantages of immunity to electromagnetic interference and no demand for power supply in site, the optical load cell has been widely applied in monitoring the ice coating of overhead transmission lines. In this paper, we have adopted the shearing structure with additional grooves as elastic element of load cell to detect the eccentric load. Then, two welding package fiber Bragg gratings (FBGs) were mounted onto the grooves of elastic element with a direction deviation of 90° to eliminate temperature effects on strain measurement without extra FBG. After that, to avoid the occurrence of load cell breakage in heavy load measurement, the protection part has been proposed and added to the elastic ...

The method comprises the following steps of: firstly, arranging tilt-temperature monitoring devices on each line conductor so as to monitor the suspension point tilt and the conductor temperature of line conductors in real time; secondly, arranging deviation angle-wind deflection angle monitoring devices on each suspended insulator string so as to monitor the deviation angles of the suspended insulator strings along the conductor direction and the wind deflection angles vertical to the conductor direction in real time; and calculating the ice coating comprehensive load and the icecoating thickness of each line conductor in real time through monitoring the suspension point tilt and the conductor temperature of the line conductors and the deviation angles of the suspended insulator strings
In Line Signal Repeaters for Transmission Line Based Electric Fences - An electric repeater for use in transmission line based electric fences. The electric repeater comprises a forward amplifier, a backward amplifier, a quad pole quad throw signal switch, and a monostable circuit. The short forward electric pulse in the transmission line is amplified by the forward amplifier, and the amplified electric pulse trigger the monostable circuit. The monostable circuit then outputs a n electric pulse with predetermined width. This electric pulse operates the quad pole quad throw signal switch such that the wire pair of the transmission line is connected to the backward amplifier and disconnected from the forward amplifier as soon as the forward electric pulse has passed through the forward amplifier. DC electric power is supplied to the forward amplifier and backward amplifier by the transmission line metal wire pair, and two pairs of capacitors are used to block this DC electric power from entering ...
Solar and wind projects can mean big bucks for communities - but only if they keep them local!. Why does ownership of renewable energy matter? Because the number of jobs and economic returns for communities are substantially higher when electricity generation from wind and sun can be captured by local hands.. This economic self-interest motivates rapid expansion of renewable energy and builds political support for a low-carbon, more local and economically rewarding energy system. This report - Advantage Local: Why Local Energy Ownership Matters - serves as a resource, especially for communities seeking independence from their electric utilities and big out-of-state projects like high voltage transmission lines..

The health effects of living/working near power transmission lines. A British study conducted by Dennis Henshaw and colleagues at the University of Bristol, published in the International Journal of Radiation Biology on February 14, 1996, found that power lines attract particles from radon gas, a known carcinogen. They have found evidence that the harmful concentrations of radon products may be present around overhead power lines. The electromagnetic fields associated with the lines can therefore concentrate a cocktail of potential carcinogens.. On November 28, 1999, The Sunday Times reported on a new study by Professor Henshaw to be published in the International Journal of Radiation Biology. The study confirms that people living near them are exposed to radiation levels dozens of times greater than the legal limit.. The research firmly links the power lines with childhood leukaemia and other forms of cancer. …In some areas children living near power lines could receive doses of 95 ...

A transducer for detecting biomolecules comprises a bottom and a top unit. The bottom unit has a set of parallel electrically conductive transmission lines thereon and probes attached to selected locations along each transmission line for binding with the target molecule. The top unit has thereon a second set of parallel transmission lines transverse to those on the bottom unit. By applying AC signals sequentially to the two sets of transmission lines, each of the probe locations at the intersection of the two transmission lines can be addressed and the response of the probe in an unfilled detector location or a complex formed by the probe and the target in a filled detector location can be measured. If the target has been labelled, than the label at each of the locations may also be detected. The device can also be used for measuring binding constants between the probe and the target and concentrations of target solutions.
Since 1966, researchers at the Carolina Population Center have pioneered data collection and research techniques that move population science forward by emphasizing life course approaches, longitudinal surveys, the integration of biological measurement into social surveys, and attention to context and environment.

Background: High voltage overhead transmission line parameters - series impedances and shunt admittances - depend on many different factors such as the conductor geometry and physical properties (including the earth return path conditions). The influence of a certain characteristic on the line parameters is not always evident. A dedicated study is therefore required to thoroughly examine the impact of various conductor characteristics on the positive and zero sequence line parameters. The need for such a study is driven by the increasing attraction of researchers all over the world to the online estimation of line and transformer parameters based on synchronized phasor measurements. Line parameter estimation algorithms described in most of the works on this topic (mainly published abroad) are built around an optimization problem solved directly for the line impedances and admittances. This results in a large vector of unknowns even for a three-phase single circuit line. Moreover, these unknowns ...

Saturdays Habitat Restoration Teams workday had Alex Cabreras fingerprints all over it. With the mantra Reduce, Reuse and Recycle embedded in Alexs character and TNCs soul, HRT straightened eight windblown Cottonwoods along the edge of one of our large ponds. This was not an issue of esthetics but a real big safety concern. Not for the safety of the humans that frequent The Cosumnes River Preserve but for the large migrating waterfoul that come to our ponds for food and shelter. The Sandhill Cranes that roost in our ponds, far too often collide with the powerlines that traverse The Preserve. TNC has petitioned the power company that owns the transmission lines to underground them or reroute them but they have respectfully declined. Alex has embarked on a course to plant the tall Cottonwoods that are native to our area, along the edges of the ponds that the cranes use. The theory is that the cranes would then have to fly over the trees, which would be tall and readily visible, to reach ...

It is important that the right portable electric power tools be available when needed. However, this is of no value if the tools are not in good working order and able to effectively and safely perform the work. Portable electric power tools not maintained and in good working order are first and foremost a safety hazard. Secondly, poorly maintained portable electric power tools will affect both the productivity and morale of those using them. The cost of providing adequate and well-maintained portable electric power tools to field personnel is small compared to the cost of lost productivity or a resulting accident.. Where does good tool maintenance start?. Good tool maintenance starts with the proper use of tools at the work site. Field personnel must know how to select the right tool for the job and then understand how to use it properly. Training in proper selection and use of these tools is key to trouble-free use and long tool life.. Manufacturers design portable electric power tools for ...
Apparatus is provided for detecting the presence of a high impedance arcing fault on an electrical circuit, particularly a high voltage power line. Detection of a high impedance fault is realized by monitoring the high frequency components of the alternating current in the circuit, and evaluating the high frequency components of each cycle of the alternating current using a microcomputer operating in accordance with a program of instructions, to determine the occurrence of a significant increase in magnitude of the high frequency components, and then to determine whether the increase exists for a prescribed period of time and follows a prescribed pattern. The high frequency components are monitored using a current-to-voltage transducer coupled to the electrical circuit, bandpass filters coupled to the transducer, and an analog-to-digital converter providing digitized samples of the filtered transducer output voltage signal.

Agreed. I work in electronics as a profession. High voltage electronics no less. Industrial size high voltage power supplies. Everything about them up to maintaining them down to component level. The comments here from people are scaring me shitless from the lack of knowledge to the over the top over complication of the problem. Electricity can and will kill you. dead. it doesnt care if its dumping into you from an AC or DC source or at what frequency. A little tickle to one person may be the correct amount at the right time to drop another who has a heart defect they didnt and will never know they had. Freezing on circuit and all the other bullshit people wax on about is meaningless when you are dead. And electricity will grab you and tear out your soul before you have a chance to fucking realize you are dead. If you honestly dont know what you are doing, then shut the fuck up and stay the hell back. A dead know it all knows nothing. Turn off your fucking ego because its going to get ...

The hypothesis of a link between proximity to power lines and leukemia was first raised in 1979 when a study was published in the American Journal of Epidemiology. The study contended that children living in homes in close proximity to an excess of electrical wiring configurations were more likely to develop cancer.[13] The ensuing public controversy has been described by John W. Farley as a health scare, and has said that there is nothing to worry about with regard to the proposed link between power lines and cancer.[14] Although, in 1996, the United States National Research Council concluded that the current body of evidence does not show that exposure to these fields presents a human-health hazard,[15] some studies have reported an association between the two, e.g. for myeloid leukemia and Hodgkins lymphoma.[16]. ...

An optoelectronic switch has been formed from a semi-insulating substrate of indium phosphide doped with a deep level impurity and disposed intermediate a microstrip transmission line. One conductor of the transmission line has a small gap in its metallization. Upon illumination of the gap by laser pulses which are absorbed near the semiconductor surface, a photogenerated electron-hole plasma forms thereby providing a conducting path across the gap turning the switch on. A process of fabricating the switch is described, an important feature of which is a heat-treatment process which improves the response time of the switch to ˜50 picoseconds. Another important part of the invention is the formation of an optically semi-transparent metallic film at the gap surface. This provides greater efficiency in the coupling of light into the device at the gap while at the same time maintaining a short electronically non-conductive gap and thus a relatively low ON-state impedance for the switch.

Virtually all distribution-level power lines (i.e. the ones on normal telephone poles) are insulated. The big HOWEVER though, is that often this insulation is decades old, and easily flakes off. Its not easy to make insulation that lasts for decades exposed to the sun and weather. Although insulation today is pretty good, it wasnt so good 30+ years ago. Consequently, a power line that originally had good insulation when installed can be very dangerous. Just touching or jostling it could flake off some insulation, creating a path to the condutor. A tree limb touching the line may be fine, but when jostled, could flake some off. Of course connections to transformers on poles, etc. arent usually insulated at all. The other big variable is the path to ground. Anything can touch a live wire if there is no path to ground (or to another wire). Birds and squirrels do it all the time. However, if the bird has a path to ground or another line, it completes the circuit and gets fried. This is a very ...
A safety circuit system for a DC driven device for use with a fluid delivery system includes a first voltage potential DC power line, a second voltage potential DC power line, a controller and a safety circuit. The first voltage potential DC power line is coupled to provide a first voltage potential to the DC driven device, and the second voltage potential DC power line is coupled to provide a second voltage potential to the DC driven device such that the second voltage potential is different relative to the first potential. The controller controls at least the first voltage potential on the first voltage potential DC power line. The safety circuit has an enable state and a disable state, in which the default state is the disable state. The safety circuit is coupled to the controller, and the controller controls the safety circuit to place the safety circuit in the enable state independently of controlling the first voltage potential on the first voltage potential DC power line. The safety circuit is

This paper presents a magnetic sensor on thin-film SOI-SIMOX that takes advantage of a previous bipolar structure, the VCBM (voltage-controlled bipolar MOS transistor) to improve magnetic response with low power consumption. The buried oxide avoids substrate currents, while keeping a high relative sensitivity, up to 50% T−1, of the sensor. The paper introduces the structure and theoretical operation regions for both electric and magnetic features. Experimental results on two devices validate the previous analysis, presenting the main figures of merit. Finally, the total device efficiency parameter is introduced ...
