Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication line due to external interference, the surge protector can conduct the shunt in a very short period […]
The fusewas invented by Edison more than 100 years ago to protect the expensive incandescent lamp. With the development of The Times, fuses protect electrical equipment from the current overheating injury, avoid electronic equipment due to internal failure caused by serious injury. When electric current flows through a conductor, the conductor will heat up because there […]
Connections of a SPD to the loads should be as short as possible in order to reduce the value of the voltage protection level (installed Up) on the terminals of the protected equipment. The total length of SPD connections to the network and the earth terminal block should not exceed 50 cm. One of the […]
