WebTransformer Turns Ratio (TTR) is one of the most common test used to assess the condition of the transformer’s windings and core. It is performed as a part of acceptance and maintenance test procedure to determine any problems due to poor design, assembly, handling, overloading, fault conditions or poor maintenance. WebIn these cases, there are two criteria used to evaluate the results. First, the measured TTR at both extreme ends of the tap changer (highest and lowest) should be within the 0.5 % tolerance from the calculated TTR. Second, for any given tap, all three phases of the transformer should have the same voltage ratios.
