What is the state of the lightning rod standing in parallel with the protective equipment or facilities?
The lightning rod is in a dead state when it is in normal condition on the protective equipment or facilities.
The lightning rod is in parallel with the protective equipment or facilities and is in a normal condition. When lightning strikes the overvoltage, the breakdown discharge and the overvoltage are cut off to protect the environment. After the overvoltage is over, the arrester is quickly restored to its normal state and resumed its normal operation.
The main function of lightning arrester through parallel discharge gap or nonlinear resistance function of intrusion flow wave clipping, reduce the overvoltage protected by equipment, so as to protect the communication lines and equipment function. Lightning arresters are not only used to protect the high voltage generated by lightning, but also to protect the operation of high voltage.
A lightning arrester is connected between the line cable and the ground, and is usually connected in parallel with the protected device. Lightning arrester can effectively protect communication equipment, once abnormal voltage occurs, lightning arrester will act, play a protective role. When a communication cable or device operates under normal operating voltage, the arrester will not work and is considered to be a circuit breaker for the ground. Once a high voltage and endangers the insulation of the protective device, the arrester immediately acts, directing the high voltage impact current to the ground, thereby limiting the voltage amplitude, and protecting the communication cables and the equipment insulation. When the over-voltage is disappeared, the arrester is restored to its original state and the communication line is working normally.
