Characteristics and Functions of the Three Phase Relay Tester

Nov 18, 2024

What is a three phase protection relay tester?

A three phase protection relay tester can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low frequency, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection, and can simulate various complex instantaneous and conversion faults for full-set testing.

Features of the three phase protection relay tester

Easy standalone operation

It can complete most of the verification tasks on-site, verify various relays and microcomputer protection, and simulate various complex instantaneous, permanent, and conversion faults for full-set testing. It is ready to use upon startup, offering convenient and quick operation.

Powerful software functionality

It can complete numerous high-automation complex verification tasks, such as three-phase differential tests, rapid transfer for plant use, backup auto-reclosing tests, and line protection synchronization reclosing, easily test and scan various protection settings, replay faults, store test data in real-time, display vector diagrams, and print reports online.

Strong self-protection

It adopts a reasonable design for heat dissipation structure, and features reliable and comprehensive protective measures and soft power startup, with certain fault self-diagnosis and lockout functions.
