Protection relays are the key to equipment life expectancy under all fault conditions. The protection relays primary purpose is the supervision of electrical networks and thereby ensure breaker tripping under short circuit or abnormal conditions.
Regardless of the technology, the MDL Énergie inc.team has all the necessary equipment and instruments for protection relays inspection and calibration.
- Programming and set point adjustments
- Relay pick-up verification
- Verification of the time delay between two point on the protection curve
- Tripping test through CT secondary injection
