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.
The magnetic balance test is a most commonly used proactive test is performed only on three-phase transformers to detect the faults in the core and to verify the imbalance in the magnetic circuit also to identify inter-turn faults in the transformer at the early stage of manufacturing work. HOW DO WE TEST TRANSFORMER MAGNETIC BALANCE? Transformer Magnetic Balance Test Procedures: 1. Keep the transformer Tap Changer in an ordinary position. 2. Apply a single-phase AC voltage on one of the terminals of the HV winding. 3. Measure the voltage between the two other HV terminals. 4. Repeat the test for each of the three phases. Left side phase Central phase Right side phase AN BN CN Voltage applied at [...]
