Reduce Electrical Load to Within Transformer Nameplate Rating

Safety Precautions: All work must be performed by a qualified electrician wearing appropriate arc-flash PPE. De-energize the load side of the transformer before performing any circuit modifications following LOTO (Lock-Out/Tag-Out) procedures.

1. Identify the circuits contributing to the current draw that exceeds the transformer's kVA nameplate rating.
2. Perform load shedding by transferring non-essential circuits to an alternative power source or a secondary transformer.
3. If the total demand cannot be reduced, install a secondary transformer in parallel (if the units are identical and compatible) or replace the existing unit with one that has a higher kVA capacity.
4. After re-energizing the system, use a calibrated clamp meter to measure the current on all three phases to ensure the new load is consistently below the transformer's nameplate rating.
5. Monitor the transformer temperature over the next 24 hours to confirm that the temperature stabilizes and no longer exhibits a rising trend under constant operation.
