The circuit resistance tester is a key tool in electrical maintenance, mainly used to accurately measure the resistance value in electrical circuits, ensuring the safe and efficient operation of the system.Core roleDetecting contact resistance1.Application scenarios: Key connection points such
1. The insulation resistance between the primary winding and the secondary winding and the casing, as well as between each secondary winding and the casing, should be measured; The insulation resistance value should not be lower than 1000M Ω;2. Measure the insulation resistance between the primary
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
