Protection Relay Test Set for Power System Testing High Precision Relay Protection Tester with AC/DC Current, Voltage, Phase Angle, Frequency and Harmonic Injection for Substation Commissioning

The Protection Relay Test Set is a universal testing platform for electrical protection systems.

It allows engineers to simulate electrical fault conditions and verify whether protective relays respond according to their configured settings.

The system can be configured with multiple current and voltage channels, digital signal processing, automated testing software and measurement inputs.

• Current injection
• Voltage injection
• Phase angle adjustment
• Frequency adjustment
• Harmonic injection
• Binary input/output testing
• Trip contact monitoring
• Operating time measurement
• Pickup/dropout testing
• Fault simulation
• Automatic test sequence
• Test report generation

The system can be used for testing:

• Overcurrent relays
• Overvoltage relays
• Undervoltage relays
• Directional relays
• Differential relays
• Distance relays
• Frequency relays
• Reclosing relays
• Generator protection relays
• Transformer protection relays
• Motor protection relays
• Feeder protection relays

• Substation commissioning
• Power plant commissioning
• Protection maintenance
• Relay calibration
• Factory acceptance testing
• Research laboratories
• Protection system troubleshooting

Can one tester support different relay manufacturers?

Yes. A universal relay test set is generally designed to test protection functions rather than being restricted to one relay brand.

Can test reports be generated automatically?

Depending on the software configuration, test results and waveforms can be stored and used to generate reports.
