- Lightning Arrester/ Surge Arrester
A lightning arrester / Surge Arrester is a device used on electrical power systems to protect the insulation of transformer and conductors of the system from the damaging effects of lightning. The typical lightning surge arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge, which is very similar) travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in to earth.Our Products is the best in the industry. with variety of range of specifications and higher withstand capacity. We provide the best quality surge arresters.
Surge Arresters Selection
The objective of arrester application is to select the lowest rated surge arrester which will provide adequate overall protection of the equipment insulation and have a satisfactory service life when connected to the power system. The arrester with the minimum rating is preferred because it provides the greatest margin of protection for the insulation. A higher rated arrester increases the ability of the arrester to survive on the power system, but reduces the protective margin it provides for a specific insulation level. Both arrester survival and equipment protection must be considered in arrester selection. The proper selection and application of lightning arresters in a system involve decisions in three areas:
- Selecting the arrester voltage rating. This decision is based on whether or not the system is grounded and the method of system grounding.
- Selecting the class of arrester. In general there are three classes of arresters. In order of protection, capability and cost, the classes are:
- Station class
- Intermediate class
- Distribution class
- The station class arrester has the best protection capability and is the most expensive.
- Determine where the arrester should be physically located.
