Testing the I/T and U/T Characteristics of the TEST-630 Microprocessor-Based Protection Relay Tester

Inverse-time protection relies on I/T and U/T characteristics to realize coordinated fault isolation in power systems. The GFUVE TEST-630 microprocessor-based protection relay tester delivers reliable testing for these critical characteristics via secondary injection.

With high-precision 6-phase voltage and current synchronous outputs, the tester enables automatic stepped variation of signal magnitude. Users configure step increments, hold durations and test ranges via front panel buttons. It can simulate diverse fault levels to trace the full I/T and U/T operating curves of protection relays.

Supported by 8 binary input channels, the tester captures relay trip signals in real time and records corresponding operating time. Engineers can compare measured curves against theoretical standards to verify action thresholds, timing accuracy and inverse-time compliance.

This test function is essential for substation acceptance, distribution network commissioning and factory type tests. It validates whether inverse-time relays operate as specified under variable fault conditions to guarantee coordinated power system protection.
