Abstract: A new passive wireless electric field sensor is disclosed. This sensor does not require direct attachment to a source of power which makes it passive. It is composed of a resonator loaded with varactors. The sensor is interrogated by a remotely located device transmitting and receiving the pulses of sine wave in the resonance frequency range of the sensor. Therefore, the sensor can be mounted in the vicinity of high voltage apparatus and interrogated from a safe distance.
