The lightning conductor pole does not absorb lightning nor do they stop it. Lighting is diverted, voltage is limited, and parallel equipment is protected. There are a variety of applications for surge conductors, from protecting a home to a utility substation. Do lightning conductors and surge conductors have the same function? Lightning conductors protect equipment from the outside, while surge conductors protect them from the inside. Surge conductors protect the system from lightning, switching, electrical faults, and other transient voltages and surges, while lightning conductors protect the system from lightning strikes and associated surges.
Lightning Conductor Poles generally have a high-voltage terminal and a ground terminal. The current from a lightning surge (or switching surge, which is very similar) is usually diverted through the conductor, to the earth, when it travels along the power line. Lightning Conductor Pole Location. Lightning conductor poles are located near equipment to be protected. AC systems connect them between phase and ground, while DC systems connect them between pole and ground. Each phase is connected to a separate conductor in an AC system.
Do surge protectors protect my devices from lightning strikes? Sadly, no. Voltage spikes and surges will be stopped by a surge protector, but a close lightning strike will result in a violent, catastrophic burst of electricity. Direct lightning current is simply too great to be handled by a tiny electronic device in a power strip, or even by a hefty UPS. What type of electricity is lightning? Direct current or alternating current? Lighting is a transient impulse. It is neither alternating current nor direct current, but a composite of both. Lightning protection earths can be tested using two methods: Fall of Potential/61.8% and Dead Earth. The Fall of Potential method is recommended and requires an electrode under test, two reference electrodes, a set of leads, and a four-pole test meter.
