How Does a Surge Arrester Work?
A surge arrester is a device that protects electrical power systems from damages caused by lighting. A typical surge arrester has both a ground terminal and a high-voltage terminal. When a powerful electric surge travels from the power system to the surge arrester, the high voltage current is sent directly to the insulation or to the ground to avoid damaging the system. Lightning and Electrical Surges When a powerful surge or a lightning strikes a particular electrical system, it damages the whole system and any electrical devices connected to the system. Electrical devices work at a certain voltage range. When these devices receive a voltage way higher than the specified voltage sufficient for their operation, they blow up or get damaged. However, electrical systems that are protected by a surge arrester do not get damaged, because the arrester ensures that the high voltage does not get into the electrical system. Diverting Lighting and Electrical Surges Using MOV The surge arrester does not absorb all of the high voltage that passes through it. It simply diverts it to the ground or clamps it to minimize the voltage that passes through it. The secret to the arrestor’s success in diverting lightning or high electrical surges is the MOV or the Metal Oxide Varistor. MOV is a semiconductor that is highly sensitive to voltage. At normal voltages, the MOV works as an insulator and does not allow current to pass through. But at high voltages, the MOV acts as a conductor. It works as a switch that is open when there is a standard AC voltage, and a switch that is closed when lightning or high voltage is present. What Causes Electrical Surges Electrical surges occur when an incident increases the electrical charge running through a power line at some point. The most popular cause of a surge is lightning. However, lightning causes electrical surges only every once in a while. During a lightning storm, lightning may strike somewhere near a power source and affect the voltage running through a power line. Sometimes, the best way to protect an electrical device from the effects of a lightning surge is unplugging it from the power source. A surge arrestor may not work 100 percent of the time because lightning can produce very high voltages that even surge arresters cannot fully handle. More often than not, electrical devices that rely on high electrical power cause electrical surges (e.g. refrigerators and elevators). The operation of these devices sometimes causes a sudden demand for electricity that upsets the flow of current in an electrical system. Even if these surges do not cause as much damage as a lightning surge, they can still inflict major damage to some electrical devices connected to the electrical system. Installing Surge Arrestors Surge arrestors are usually installed near an electric meter to protect the electrical system of a home or building from the effects of power surges coming from the outside. A surge arrestor can protect other electrical equipment connected to the power source, but may not provide total protection against surges that come from faulty wiring or the overall electrical functioning of household or office electrical appliances.

Surge Arresters
A surge arrester is a product installed near the end of any conductor which is long enough before the conductor lands on its intended electrical component. The purpose is to divert damaging lightning-induced transients safely to ground through property changes to its varistor in parallel arrangement to the conductor inside the unit. Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS), they are only designed to protect against electrical transients resulting from the lightning flash, not a direct lightning termination to the conductors.   Lightning termination to earth results in ground currents which pass over buried conductors and induce a transient that propagates outward towards the ends of the conductor. The same induction happens in overhead and above ground conductors which experience the passing energy of an atmospheric EMP caused by the flash. These devices only protect against induced transients characteristic of a lightning discharge's rapid rise-time and will not protect against electrification caused by a direct termination to the conductor. Transients similar to lightning-induced, such as from a high voltage system's switch faulting, may be safely diverted to ground, however, continuous overcurrents are not protected by these devices. The energy in the transient is infinitesimally small in comparison to that of a lightning discharge; however it is still of sufficient quantity to cause arcing between different circuit pathways within today's microprocessors.   Without very thick insulation, which is generally cost prohibitive, most conductors running for any length whatsoever, say greater than about 50 feet, will experience lightning-induced transients some time. Because the transient is usually initiated at some point between the two ends of the conductor, most applications install a surge arrestor just before the conductor lands in each device to be protected. Each conductor must be protected, as each will have its own transient induced, and each SPD must provide a pathway to earth to safely divert the transient away from the protected component, be it instrument or computer, etc. The one notable exception where they are not installed at both ends is in high voltage distribution systems. In general, the induced voltage is not sufficient to do damage at the electric generation end of the lines; however, installation at the service entrance to a building is key to protecting downstream products that are not as robust.
