CT 85HC Partial Discharge Current Transformer


Manufacturer: Qualitrol show products

The CT85 wide-band current transformer is designed to acquire partial discharge (PD) pulses from generator or motor windings. Its high saturation current and intrinsic suppression of very low frequencies makes it an ideal sensor for installation around high voltage power cables. The measurement is contact free. No galvanic connection to the high voltage terminals is made.

Description

The CT85 wide-band current transformer is designed to acquire partial discharge (PD) pulses from generator or motor windings. Its high saturation current and intrinsic suppression of very low frequencies makes it an ideal sensor for installation around high voltage power cables. The measurement is contact free. No galvanic connection to the high voltage terminals is made.

The CT can be opened so that no high voltage cable has to be disconnected for its installation. The CT is available as a standard model and with certificate for EX environment (hazardous atmospheres).
