T&R Test Equipment is renowned for its rugged, reliable and
innovative relay test equipment solutions. The DVS3 mk2
voltage source and 50A-3PH current source provide the
commissioning and maintenance engineer with a flexible 3
phase relay test system at a realistic price.
The units may either be used together to test directional and
distance protection, or individually to test single and three
phase voltage (DVS3) and current (50A-3PH) relays.
The DVS3 also excels in testing G59 embedded generation
protection, including voltage, frequency, vector surge and
df/dt (ROCOF) relays.
The DVS3 runs from a 230V single phase supply, and the
50A-3PH from a 400V 4 wire, 3 phase supply. An optional
delta-star supply converter is available, allowing the DVS3
and 50A-3PH to use a 115V, 230V, 400V or 440V 3 phase 3
wire supply.
