Learn about essential lightning protection measures for substations and transformers, including the use of lightning rods, surge arresters, and protective gaps on both high-voltage and low-voltage sides to ensure reliable electrical system performance. Lightning and surge protection may only be installed, put into operation and maintained by qualified electricians who are familiar with national and international laws, regulations and standards. Among other things, standardized requirements for line lengths, effective protection areas and fuse. Our light-ning and surge voltage protection systems are per-fectly matched to one another and to the requirements in the different zones – from the air-termination device, which must arrest the full energy of a lightning strike, through to fine power protection, which eliminates the last voltage. Establishes the four lightning protection levels (LPL I–IV) with associated lightning current parameters. Provides the risk assessment methodology. Defines risk components R1–R4, tolerable risk values, and the decision framework for whether lightning protection is required and at what level. Covers. rocess approved by the American National Standards Institute. This process brings together volunteers representing varied viewpoints and i terests to achieve consensus on fire and other safety issues.
