Electrical Relay Calibration Services (OC & EF Relays)

Borang H

We provide professional inverse time overcurrent (OC) and earth fault (EF) relay calibration services for land-based electrical systems. Our team ensures that each relay is accurately tested, verifying trip times and current settings to meet design and safety requirements.

The calibration process typically takes 30 minutes to 3 hours, depending on relay type and complexity. After testing, we issue a full calibration certificate along with Borang H for regulatory compliance under the Energy Commission (Suruhanjaya Tenaga).

Our service guarantees reliable electrical protection, traceable documentation, and peace of mind for both operators and facility managers.
