Abstract study lightning protection system at bts (base tranceiver station) in pt. telkomsel banda aceh by khusnul khatimah 1504005010032 lightning causes disturbance to electric power system. mechanism of disturbance in instruments consist of resistive, capasitive, and inductive coupling. requirement of lightning protection use classification area of the structure or calculation with thunderstorm days parameter, ng, nd, and nc. lightning protection must consist of external protection, internal protection, and grounding system. methods to determine air termination are meshed size, angle protection and rolling sphere method. to optimize lightning protection installation, protection area divide into several parts which is know as lightning protection zone. lightning proctection system which is installed in bts (base transceiver station) must be increase base on rolling sphere method analysis. keywords: lightning protection system, lightning effect, rolling sphered method, bts.
