The transformer turns ratio is the number of turns of the primary winding divided by the number of turns of the secondary coil. The transformer turns ratio provides the expected operation of the transformer and the corresponding voltage required on the secondary winding.
Single-Phase TURA series devices can test transformer turn ratio and calculate error as a percentage. By testing the turn ratio operator can understand how much voltage they will get from the secondary side precisely. TURA single-phase series turn ratio meters can test three-phase transformers also.
TURA-03 series turn ratio meters can test turns ratio by making only a one-time connection to transformers and automatically test all phases. TURA-03 series turn ratio testers can make automatic vector group detection and calculate ratio error. Tura-03 series turn ratio testers are very easy to use with the 7-inch display and user-friendly interface.
