Description
Product Description

The Overcurrent Relay Test Set is designed to verify the operating characteristics of overcurrent and earth-fault protection relays.

By injecting controlled current signals into the relay, engineers can determine pickup current, operating time and protection characteristics.

Testing Functions
  • Instantaneous overcurrent
  • Definite-time overcurrent
  • Inverse-time overcurrent
  • Earth-fault protection
  • Phase overcurrent
  • Pickup current
  • Dropout current
  • Operating time
  • Time-current characteristic
  • Trip contact testing
Applications
  • Feeder protection
  • Distribution protection
  • Transformer backup protection
  • Motor protection
  • Generator protection
  • Industrial electrical systems
Customer Pain Points

“Does the relay trip at the correct current?"

Pickup testing verifies the actual operating threshold.

“Does the relay operate within the required time?"

The tester measures relay operating time after current injection.

“Is the inverse-time curve correct?"

Automated test software can test multiple current points and compare actual performance with expected characteristics.

FAQ

Can it test inverse-time overcurrent relays?

Yes, if the corresponding software/test module is supported.

Can it test earth-fault protection?

Yes. Earth-fault and residual-current protection can be tested by applying the appropriate current conditions.
