Power Transformer Pre-Commissioning Tests

Transformer is the most important equipment in the electrical power transmission and distribution system. In order to ensure availability of uninterrupted power supply, it is essential that the condition of trans-former is continuously monitored during service as failure of transformer would result in interruption of power supply resulting loss of industrial production and inconvenience to customers on large scale.

This course aims in providing participants clear under-standing of the basic constructional features of power transformers, various processes during manufacturing, various fittings and accessories, type tests and routine tests in manufacturers works, pre dispatch precautions, Non destructive diagnostic measurements to access present condition of transformers, installation at site, pre-commissioning testing including diagnostic tests and commissioning of the trans-former and preventive maintenance practices.

Electrical and mechanical/ power engineers, project engineers, maintenance engineers and supervisors and operating staff of electrical sub stations will find this course very useful for enhancing their knowledge related to transformers and its working principles, de-sign, operation & maintenance. The course will also definitely be beneficial for the all the other department people concerned with the plant operations, production, maintenance and safety. It could be also useful for the procurement and quality personnel.
