The winding resistance test of a transformer is conducted using a precision ohmmeter or a transformer testing system specifically designed for this purpose. The procedure involves disconnecting the transformer from the power supply and ensuring its safety. Connect the ohmmeter leads to the winding terminals, making sure to select the correct winding to test. The transformer testing system applies a low measurement current and records the resistance value. This test helps identify issues like poor connections or damaged windings, ensuring the transformer operates efficiently and reduces the risk of failure. Regular testing is crucial for maintenance and compliance with industry standards.
