A surge arrester, also known as a “surge protection device” or transient voltage surge suppressor” works toward the same goal, but performs a slightly different function. Different surge arresters are available based on their withstanding capability. A surge arrestor, on the other hand, will intercept the surge from a lightning strike and send the energy into the grounding wire or another grounding area. How to Calculate/Find the Rating of Transformer in kVA (Single Phase and Three Phase)? For example, when an inductive load is switched off, it generates voltage surges (also known as switching surges) in the system following the self inductance laws of back EMF. Surge arresters against lightning Description of the installation. Surge arrester protects the installation from inside while lightning arrester protects the equipment from outside. Bộ chống sét lan truyền (surge arrester) hoạt động để giảm thiểu điện áp tăng đột biến trong nhà của bạn bằng cách truyền công suất dư thừa trực tiếp vào ổ cắm kèm theo hoặc dây tiếp đất, giảm nguy cơ hư hại cho các thiết bị đắt tiền. This table documents how well the arrester clamps lightning and switching surges, which is the fundamental purpose of arresters. Your email address will not be published. Lightning rod is cheaper than surge arrester which is mounted on the top surface of a building or power lines tower which provides a safe path to the high value electrostatic charges and lightning currents to the ground (it must be properly earthed to the grounding system as well). An example of this would be a problem caused by complications with the power grid or lightning. It’s easiest to think of an arrestor (and this goes for a lightning arrestor as well) as a form of protection from external problems, such as those caused by lighting or power grid … Need some help getting the ideal electrical protection system for your home? They absorb the electrical surges in the transmission tower itself. These pulses could harm the sensitive devices especially electronic devices. This example is for a station class arrester but can be used to understand all discharge voltage tables of all arresters. Surge arrester: Very nice , Please I am an apprentice in electricals and solar installation are there any books,audio tapes or articles you could recommend? Surge arresters, which bring together cutting-edge technology for protecting the power grid from the threat of lightning strikes, are gaining attention in both advanced and developing countries. These are typically installed directly into the network in a whole-home protection system, or can be found in simpler tools like an outlet-expanding surge protector. However, that said, it’s always best to consult a trained and certified electrician! Joined Sep 24, 2015 5,831. Step by Step Procedure with Calculation & Diagrams. That means, should you require a more precise or complex solution than “any one will do,” you’ll have the benefit of a specialist who can direct you to the ideal installation. 1963. Proudly Serving Hillsborough, Pinellas, Pasco, Sarasota, & Manatee Counties. If a bolt of lightning were to strike, the lightning arrester directs the excess energy away from the house and toward the ground. There is a simple difference between a surge arrester and a lightning arrester. Contact Hoffman Electrical & A/C online. Most noteworthy for this topic is the confusion with “surge arrester,” which is typically confused with “surge suppressor.” These two items both serve to protect your home electrical network, wiring, and appliances. The main problem with them is that they are designed for protecting large electrical distribution systems from lightning surges, and not for sensitive solid state equipment. One type of arrester protects your home from the outside. The pulley wheel electrodes are replaced by ceramic-bonded shunt resistors and a series spark gap. Lightning Arrester is a protective device used to protect the circuit from lightning strokes having high transient voltage surges, surge currents due to lightning, spark and isolation arcs etc. Ready to install lightning arresters in your home or at your commercial property? 24 KV Gray MOA Electronic Polymeric Polymer Lightning Arrester Used in Substation Both types of arresters are used to protect your home in case it is hit by lightning. 2005 Selection and ordering data 1) The devices can be coupled to instabus KNX EIB and AS-i bus or PROFIBUS through floating changeover contacts. Should lighting strike your home, the lightning arrester, installed externally, would attempt to immediately detour the electricity away from your home and appliances and direct it instead to safe ground. Talk to a professional electrician to find out what the best options are.
