Surge Arrester

A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. It prevents continued flow to follow current to ground and it is capable of repeating these functions as specified per ANSI standard C62.11. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed in parallel.

Surge arresters have many applications, anywhere from protecting a home to a utility substation. They are installed on circuit breakers inside a residential home, inside padmounted transformers, on pole mounted transformers, on pole-mounted riser poles and substations

The distribution power line will see various voltage surges. Lightning is the main source of voltage surges. There are approximately 100 lightning strikes on the Earth's surface every second. Lightning is a random and unpredictable event.

Other sources of voltage surges include switching surges and temporary overvoltages. Switching surges are overvoltages produced by changes in operating conditions within the system and are the main voltage surge for station-class arresters. Switching surges is the trapping of energy and the subsequent release of the energy. Temporary overvoltages result from ground faults on one phase and voltage rises on unfaulted phases until the fault can be cleared.
