Non-contact long range AC voltage measurement
2019 IEEE SENSORS, 2019Safety requirements and physical constraints often prohibit contacting high voltage terminals. This limits the options for monitoring and maintaining high voltage machinery and power distribution grids. We present a non-contact AC (alternating current) voltage and frequency measurement system with 600 mm of operation range to overcome this issue.

A Non Contact Voltage Measurement Technique using Auger Spectroscopy
21st International Reliability Physics Symposium, 1983Scanning Auger spectroscopy is commonly used for surface analysis to identify elements on a given sample. The identification is accomplished by the use of an electron spectrometer that determines the energy of electrons leaving the sample surface. The energy of the Auger electrons leaving the sample is characteristic of the element.
