The Working Principle of 66Kv Surge Arresters

The working principle of 66kV surge arresters revolves around their ability to protect electrical equipment and communication lines from high-voltage surges. When operating under normal conditions, where voltage levels are within standard limits, the surge arrester remains passive, essentially creating an open circuit to the ground.

However, when a sudden surge of high voltage occurs—potentially endangering the insulation of the equipment—the 66kV surge arrester swiftly responds. It conducts the excess current to the ground, thereby limiting the amplitude of the voltage surge. This action helps prevent damage to the communication cables and equipment by diverting the harmful electrical energy away from sensitive components.

Once the transient overvoltage subsides, the 66kV surge arrester resets automatically to its initial state. This ensures that the communication line can resume normal operation without any residual effects from the surge event. The effectiveness of 66kV surge arresters lies in their rapid response to protect against voltage spikes and their ability to maintain the integrity and reliability of electrical systems during transient events.

The Function of 66Kv Surge Arresters in Communication Equipment Protection

When the communication cable or equipment is operating under normal operating voltage, the 66kV surge arrester will not have an effect, and it is regarded as an open circuit for the ground. Once a high voltage occurs, and the insulation of the protected equipment is endangered, the arrester immediately acts to direct the high-voltage inrush current to the ground, thereby limiting the voltage amplitude and protecting the communication cable and equipment insulation. When the overvoltage disappears, the 66 kv lightning arrester quickly returns to its original state and makes the communication line work normally.
