The newly developed T100 single phase relay tester has been launched in Vietnam successfully this April. Users in Vietnam are pleased to see that T100 is so powerful and easy to use. Besides manual operation it also provides auto test modules, such as ‘Shot’ and ‘Ramp’.
T100 (type 01) single phase relay tester has one specially designed UI output, which can change the phase angel smoothly and thus makes the accurate test of directional relay possible. This feature also makes T100 very different to other similar products, where accurate phase angle control is not available.

The digital substation is becoming the trend in the world and it's developing particularly fast in China now. To provide the proper solution for IEC61850 complied digital relay test PONOVO has launched its PWF series digital relay testing system. It has 3 fiber optical ports and one Ethernet port. The PWF has the built-in GOOSE interpretation facility. Thanks to its three fiber optical ports PWF can communicate with 3 relays simultaneously. This is especially useful when testing differential relays where 3 fiber optical ports are the required. Dozens of digital relays have been tested sucessfully by PWF. The relays tested including GE, Siemens, Nari, etc.
