Transformer testing is intended to make sure that electrical and mechanical systems are functioning correctly so that safety and performance of the equipment is assured. In order for transformer equipment to operate correctly, voltage, cycle and stressors must be maintained and tested. Additionally, the equipment’s location plays an important role in determining the needed maintenance to keep it operational.
Some of the required procedures for testing transformers:
Technicians will perform system cleaning and visual inspection to make sure there is no damage. Part of this inspection includes looking for any indications of overheating, grounding issues, corrosion, loose blocks and insulation defects. At this time, it is a good idea to exam for any leaks from oil or nitrogen.
Megger Insulation Test
Measuring the insulation resistance evaluates the condition of insulation. It will show signs of moisture or insulation wear and allows for benchmarking of test results for future comparisons.
Power Factor Test
Also called a Doble test, the power factor testing makes sure that the insulation is functioning correctly within the transformer system itself. The strength of insulation indicates whether power is being lost through current leaks within the insulation.
Low Voltage Testing
Voltage tests help technicians know that the main components of the transformer are still performing optimally.
