RIV1

Radio Influence Voltage (RIV) measurement calibrator

Reliable partial discharge testing on transformers

Our RIV1 calibrator is used for the calibration of high-voltage partial discharge (PD) test set-ups on power, current and voltage transformers. It ensures the reliable calibration of MPD 500 and MPD 600 measurement systems for PD measurements based on Radio Influence Voltage (RIV) according to NEMA and CISPR standards. A voltage is injected across the test object at a pre-defined frequency within a range of 100 kHz to 2 MHz and thereby adapted to surrounding noise conditions.

Versions for different standards

The RIV1 comes in two versions, each with different output impedances to meet different standards. The RIV1-NEMA ensures a low output impedance (<2 Ω) required for a very stable output voltage to meet standards like NEMA 107-1987 or IEEE C57.12.90. The RIV1-CISPR provides an output impedance of 20 kΩ required by standards like CISPR 18-2 (2) and by IEC 60437.
