AC Test Function Operation of TEST-630 Microcomputer Protection Relay Tester

 The GFUVE TEST-630 provides comprehensive AC test operation functions, serving as the core secondary injection testing solution for power system protection relays. It delivers standard and fault-state AC signals to fully verify relay operating performance and protection logic.

Adopting high-precision 6U6I synchronous AC output, the tester supports flexible adjustment of voltage, current, phase angle and frequency. It can simulate normal operating conditions, phase faults, ground faults and unbalanced three-phase states, covering almost all AC fault scenarios in power grids.

With high-sensitivity binary input channels, the device stably captures relay tripping, closing and state switching signals during AC testing. It accurately measures operating time, action thresholds and logical response to ensure consistent and reliable protection behavior under various AC working conditions.

Widely applied in substation commissioning, power system maintenance and laboratory relay calibration, the AC test operation ensures all AC-based protection functions operate accurately, laying a solid foundation for safe and stable power grid operation.
