Key Testing Functions
1. Turns Ratio (TTR) Measurement
Confirms the voltage ratio between primary and secondary windings.
Detects coil deformation, insulation degradation, and winding faults.
2. Vector Group and Polarity Testing
Determines the vector group, phase angle, and polarity of the transformer.
Prevents phase mismatches in power grid connections.
3. Excitation Current Measurement
Measures the magnetizing current of the transformer core.
Identifies core saturation, winding defects, and insulation deterioration.
4. Deviation Analysis
Compares the measured turns ratio with the rated value.
Alerts the operator to any abnormal deviations indicating faults.
