OLTC

Turn Ratio Testing

Turns ratio test performs on transformer to check the voltage ratio between primary and secondary side because the voltage in primary and secondary coil depends on the consequent number of turns in primary and secondary coil.

The transformer turns ratio (TTR) test detects shorts between turns of the same coil, which indicates insulation failure between the turns. These tests are performed with the transformer de-energized and may show the necessity for an internal inspection or removal from service.

OLTC Overhauling & Servicing

Inspection Stage

A team of our service engineers would visit you, to inspect and analyze the transformers and OLTC. Inspection helps us to analyze customers requirements and transformers condition so we can plan for the future work which is to be done

Overhauling Procedures

After the inspection and based upon the measured data, suitable course of Overhauling Procedure is recommended to improve the reliability & the Life of equipment. However, at least once in a 5 Years, overhauling is essential to restore the health of equipment.

Commissioning Stage

All the Chemical & Electrical Tests are performed before commissioning of the equipment to ensure the Integrity and for obtaining the future reference values.
