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
Absorption ratio is an important indicator used to evaluate the insulation performance of electrical equipment, especially in devices such as transformers and motors. It refers to the ratio of insulation resistance values measured at two different time points after applying a DC voltage. The most co
Pour point and solidification point are important indicators used to describe the fluidity of liquids, especially oils, under low temperature conditions. They are all key parameters for measuring the low-temperature performance of oil products.I、 Pour a little1. Definition: Pour point refers to the
Power Quality (PQ) refers to the quality of electrical energy in the power system, mainly including voltage quality, current quality, and frequency quality, which directly affects the stability and safety of the power system, as well as the performance and lifespan of electrical equipment.
