Each piece of electrical equipment in an electrical system needs to be protected from voltage surges. The arresters shall be rated at 10kv. mounting of combination cutout-lightning arrester units, terminations or single cutouts that require only one bolt for mounting. According to IEC 61312-1, it is to be assumed that approximately 50 percent of any lightning current is conducted via the external lightning protection system (lightning arrester) into the ground. 0 Product Catalogue. Any other independently grounded building system in close proximity to lightning protection components would be at 0 volts,. Each of circuit breakers 18 and 22 occupies a one-half inch wide space and each of surge arrestors 26 and 28 also occupies a one-half inch wide space, so that the entire circuit breaker/surge arrestor package 30 illustrated in FIG. Where, I r and V r are the reference current and voltage respectively of the lightning arrester or surge arrester block. While the design of the mast incorporated a well-designed lightning. Lightning arrester protects power system lines and telecommunications system on damaging effects of lightning. POWER SYSTEMS, INC. Voltage grading rings are included for arresters rated 172 kV and above. For use when requirements of lightning in-tensity, energy capability and pollution are moderate. 4 Distribution Products Catalog CA08101001E—November 2010 www.
