Scientists have developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices. TU Wien has developed a sensor ...

A new device and technique have been developed by National Institute of Standards and Technology researchers for measuring "breakdown" voltage -- the voltage required to produce electrical arcs when ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...

Electricity is a key aspect of life, and is required for organisms to move and communicate. The movement of tiny charged particles called ions across the membranes that enclose cells are what ...

MR. ASPINALL PARR has aimed at giving a description of all the leading electrical measuring instruments on the market, and he has carried out this object with a painstaking thoroughness worthy of a ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

New equipment which can conduct ECG-examinations of fetuses based on the NBI-method could have a significant impact on future treatment, say scientists. New study describes an experiment which ...

Partial discharge in electrical equipment insulation can lead to catastrophic failure. NETA Certified Technicians must understand the reasons partial discharge may occur and how to properly detect, ...

Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on ...
