Lightning arresters can effectively and promptly protect electrical equipment. As long as there is abnormal voltage in the system, the arrester will play its role. When the protected equipment is operating under normal voltage conditions, the arrester will not function, which means it is a circuit break to the ground. However, when high voltage occurs and threatens the insulation of the protected equipment, it will be activated immediately and introduce the high voltage into the earth. This effectively limits the amplitude of the voltage and can protect electrical equipment. .
Moreover, when the high voltage no longer exists, the arrester will return to its previous dormant state very quickly, allowing the system to continue normal power transmission and distribution. The arrester mainly works through parallel discharge or non-linear resistance, and then cuts the amplitude of the intruding flow wave, which can help reduce the high voltage suffered by the protected equipment. It can protect both atmospheric high voltage and operating high voltage.
There are many types of lightning arresters, but each type of lightning arrester has its own advantages and characteristics, so we need to use it according to different environments to achieve good lightning protection effects.
