Since I started the commissioning work 30 years back, transformer commissioning consisted of more tests, but nowadays, the number of tests has been reduced due to costs and time-saving. This article will go through complete testing that needs to be done at the site during the commissioning process of the transformer. These tests include winding insulation resistance test, winding resistance test, vector group test, tan delta test, no-load test or iron losses, load test or copper losses, temperature rise test, partial discharge test, frequency response analysis test, and transformer oil breakdown test.
