NEMA Arresters Section Publishes Guidance Documents and Videos

The National Electrical Manufacturers Association (NEMA), on behalf of its Surge Arresters Section, has published six guides and accompanying videos on arresters. These include four guides on purchasing good quality arresters, an instructional document on protecting distribution lines from lightning, and a document on the uses of transmission line arresters.

In today’s global market, there are a far greater number of arrester options, making the best choice more difficult to determine. The topics of these guides were chosen to educate utility buyers and engineers on the advantages of thoroughly tested and well-manufactured products. NEMA member products are manufactured to meet high quality standards to ensure reliable performance in the field.

The guidance documents may be downloaded at no cost on the NEMA Arresters website:
