8. TESTING POWER TRANSFORMERS - Aventri

checks, especially when UL tap changers need to be operated to perform various tests. Changing tap positions manually by hand cranking the mechanism is a slow and tiresome process. 8.5 CT TESTS Transformer bushing CTs should be tested using the Current Ratio test method before the transformer has been completely assembled.
