SIMULATION OF A CAPACITIVE SENSOR FOR PD REGISTRATION IN POWER CABLE
Dmitry A. Polyakov, S. A. Romantsova · Actual Issues Of Energy · 2023
The article discusses the simulation of a partial discharge (PD) pulse in a power single-core coaxial cable using a capacitive sensor. The sensor provides capacitive coupling to the test sample and its capacitive element is in fact part of the total capacitance of the cable. The resistive element added to the design makes it possible to register current pulses of partial discharges. At the same time, the used sensor has no connection with high-voltage electrodes of the systems, which is its undoubted advantage in comparison with conventional capacitive sensors.
