Overload Operation Guidelines

Proper transformer loading is essential to ensure safe and reliable operation.

Continuous operation above the rated current can increase winding temperature, accelerate insulation aging, and reduce transformer lifespan. Excessive overload may also lead to insulation damage, inter-turn short circuits, overheating, and eventual transformer failure.

To ensure long-term reliability:

• Monitor three-phase load currents regularly.

• Keep three-phase current balanced.

• Maintain current imbalance within the recommended limits.

• Avoid prolonged overload operation.

Routine inspections and preventive maintenance help maximize transformer efficiency and service life.
