Transformer Winding Resistance Ohmmeter/Transformer DC Resistance Tester - Test Precautions and Features? The test precautions and core features of the transformer DC resistance tester are as follows: I. Test Precautions 1. Safety First, Thorough Discharge: Before testing, ensure the transformer is completely de-energized and reliably grounded. After testing, the windings will store a large amount of charge. Thorough discharge must be performed using the instrument's discharge function or a dedicated discharge rod before changing the wiring to prevent electric shock. 2. Accurate Temperature Measurement, Result Correction: The actual winding temperature must be accurately measured and recorded...

On-Load Tap Changer Analyzer/On-Load Switch Tester - Test Precautions and Features? The test precautions and core features of the on-load tap changer tester are as follows: I. Test Precautions 1. Safety Isolation and Discharge: Before testing, ensure the transformer is completely de-energized and fully discharge the oil chamber and windings of the on-load tap changer. Always disconnect the operating power supply of the switch body motor to prevent accidental starting. 2. Oil Level Check and Correct Wiring: Check that the on-load tap changer oil level is normal. The test leads should be directly and securely connected...
