Power capacitors, capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium form a capacitor. The capacitance of a capacitor is determined by its geometric size and the characteristics of the insulating medium between the two plates. When a

Single-phase distribution transformers are small in size and light in weight. They can penetrate into the load center to the maximum extent, shorten the radius of the low-voltage network and reduce losses. This type of transformer can be installed on a pole, which is easy to install and can reduce m

1. Development history of resistance tester:The loop resistance tester tells everyone that since the cable has been buried, the detection of the resistance tester has become a problem that must be solved. Initial cable fault roughing is performed using the bridge test principle. At that time, resist

Relay protection is a very important technology in the power system. Its function is to promptly remove the fault area when a power system fault occurs to protect the safety of equipment and personnel. In the substation, the relay protection system plays a vital role. It can identify faults in the p
