Transmission Line Surge Arrester (NGLA) upto 400kV, Power supply utilities have verified load losses due to voltage snags on their systems from transitory outages caused by lightning activity and causing permanent damages. The effect of these transitory disturbances on transmission lines are more critical in areas with high ground resistivity when associated with high lightning activity. Most non-scheduled outages are transitory in nature, with a fault time shorter than 1 minute, yet deemed to be unacceptable by power supply utilities. The loss of supply is critical for all modern industries reliant on sophisticated electronic equipment and production processes sensitive to momentary disturbances to the system. Raychem RPG’s Transmission Line Surge Arresters (TLA) provides reliability to the power system by reducing non-schedule outages caused by lightening.
