Solid state electric field sensor

چکیده
Power measurement systems, such as Phasor Measurement Unit (PMU) structures, require installation of special voltage and current instrument transformers connected to the energized conductor to collect data from the power line. While non-contacting methods of current monitoring are already well known and implemented, the contactless voltage monitoring is still lacking. This paper describes a tunable capacitance solid state electronic structure that is very promising in its electric potential measurements. The sensor is capable of the voltage monitoring on energized wires and unshielded cables in a non-contacting fashion. The theoretical background of the sensor operation along with experimental results are presented.
