Lightning Arrester For Buildings

The lightning arrester for buildings doesn’t absorb or stop lightning, but rather protects against dangerous energy. This device protects parallel equipment from lightning, limits the voltage, and diverts the lightning. There are many applications for surge arresters, from protecting homes to protecting utility substations. How do lightning arresters and surge arresters differ? Lightning arrester for buildings provides protection from outside, while Surge Arrester For Home offers protection from inside. While surge arresters protect the system from lightning, switching, electrical faults and other transient voltages and surges, lightning arresters are mostly used to deal with lightning strikes and associated surges.

Lightning arrester for buildings is the correct way to combat these dangerous electrical currents, as a common surge protector will only stop voltage spikes and surges, but not the violent, catastrophic surge of current caused by lightning. Whether it’s an electronic device in a power strip or a UPS, direct lightning current is simply too big to protect. Is lightning an AC or DC current? The impulse is transient. It is neither AC nor DC, but a combination of both. A lightning protection earth can be tested both by the fall of potential/the 61.8% test and by a dead earth test. This method is a fall of potential method and involves a four-pole test meter, two reference electrodes, a set of leads, and two electrodes under test.

Lightning arresters for the home usually have two terminals, one for high-voltage, one for ground. If a lightning surge (or a switching surge, which is a very similar event) travels along the power line to the arrester, the surge’s current is usually diverted through the arrester, and the surge is sent to earth. Location of the Lightning arrester for buildings. The arrester is located near the equipment that needs to be protected. In an AC system, they are typically connected between the phase and ground. In an DC system, they are usually connected between the pole and the ground. Separate arrester circuit breakers are used in AC systems.
