Abstract
When electric field calculations on the surface of electrodes and electrical insulation present difficulties due to complex geometries and diverse dielectric properties, it is sometimes very useful to resort to direct measurements. However, conventional probes, based on the capacitive effect, are not quite suitable for this purpose due to strong perturbations introduced by probes themselves and to difficulties in isolating the sensors from the instrumentation at points of measurement with a high potential. To avoid these difficulties, a measurement system was developed which incorporates a Pockels effect crystal sensor, a moveable HeNe laser beam for signal transmission and beam polarization modulation, and a laser beam analyzer which detects variations in polarization induced by the sensor. This paper describes the key design, operation and performance characteristics of this device.
