In the power system, VT (Voltage Transformer) and PT (Potential Transformer) are essentially the same type of equipment, both belonging to voltage transformers. Their core function is to proportionally convert high voltage into low voltage for use in secondary equipment such as energy metering, rela

1. Connect the power supply, connect the current output terminal to the primary side of the tested current transformer, and connect K1 and K2 to the secondary side of the current transformer. Short circuit the normally closed switch, otherwise the test cannot be carried outPS： In practical applicat

The load state of a transformer refers to the load it bears during actual operation, which reflects the working condition and health level of the transformer.Copper loss (also known as wire loss or resistance loss) is the energy loss caused by the current passing through the winding of a transformer

Demagnetization refers to the elimination or reduction of residual magnetism accumulated in power equipment due to long-term operation through specific methods. Residual magnetization can have adverse effects on the performance and safety of equipment, therefore demagnetization is one of the importa
