Working Principle
The Three Phase Relay Protection Test Unit works by simulating various fault conditions in a power system network and measuring the performance of protective relays under these conditions. The unit generates three-phase AC voltage signals and applies them to the input terminals of the protective relay being tested.
The unit is equipped with advanced digital signal processing technology that allows it to generate a wide range of fault conditions, such as overcurrent, under/overvoltage, directional, distance, and differential faults. These fault conditions are created by manipulating the amplitude, phase, and frequency of the AC voltage signals.
During the test, the protective relay being tested is monitored for its response to the simulated fault conditions. The performance of the protective relay is measured and recorded, including its trip time, trip current, and other relevant parameters.
The Three Phase Relay Protection Test Unit is designed to operate safely with protective relays and other devices, with built-in protection features such as overcurrent protection, short-circuit protection, and grounding protection. The unit also has a user-friendly interface that allows for easy operation and data analysis.
