Power transformers are among the most strategically important and expensive components on any network. Data on their health is therefore vital for effective asset management. Recent advances in techniques for measuring and analysing the condition of transformers have made diagnostic testing more cost effective and valuable than ever.
AMEC’s skilled testing engineers are equipped with the latest electrical testing equipments and can provide on site testing of your transformers. We specialize in the following transformer tests:
The SFRA test is suitable for power transformers and can detect various faults including shorted turns or open winding, axial deformation, partial winding collapse, hoop buckling, broken or loose clamping structures for winding/core etc. AMEC provides sweep frequency testing as one of the many diagnostic tests to help determine the health and condition of your transformer.
Power factor testing of electrical insulation is one of the most recognized and highly regarded procedures in both preventive maintenance process and manufacturing of electrical power apparatus such as transformers, reactors,cables, electromechanical rotating machines etc.
Electrical properties of the insulating system change over time. The principal contributor to the unexpected breakdown of the high voltage equipment is insulation failure. By measuring the electrical properties of oil, it is possible to ensure the operational unexpected breakdown. Tan-Delta is one of the most powerful diagnostic tool to monitor the condition of insulating medium of various HV equipment.
