Relay Test Sets
Relay test sets inject controlled current and voltage into protection relays and measure when they operate, so you can confirm pick-up values and trip times for overcurrent and similar relays.
- Overcurrent relays
- Earth fault relays
- Substation commissioning

- 1
Single phase or three phase
Single-phase sets cover overcurrent and earth-fault testing. Three-phase sets are for testing relays that need phase relationships.
- 2
Current rating and duty cycle
Check the maximum current and how long the set can hold it. High currents are usually available only for short periods.
