3 RTE DEADFRONT 9 KV ELBOW SURGE ARRESTOR 3237015C09M
The Cooper Power Systems VariGAP M.O.V.E. Surge Arrester incorporates the latest in metal oxide varistor (MOV) and resistance graded gap technology in a premolded rubber elbow. The arrester provides overvoltage system protection in an insulated, fully shielded, submersible, deadfront device. With this unique combination of technologies, Cooper Power Systems has advanced the performance characteristics of deadfront arresters beyond previously attainable limits.
The VariGAP M.O.V.E. Arrester is a combination of both metal oxide and gapped arrester technologies. Construction consists of metal oxide varistors in series with a non-linear resistance graded gap structure. The mating of these two service-proven technologies results in a sharing of voltage during steady state conditions, minimizing voltage stress on both components. This results in a significant improvement in protective characteristics.
The VariGAP M.O.V.E. Arrester is designed with a 60 Hz sparkover of 1.5 times its duty cycle rating. This feature ensures a temporary overvoltage (TOV) capability greatly in excess of that available with gapless metal oxide arresters.
The arrester housing interface conforms to IEEE Standard 386 Separable Insulated Connector Systems. The arrester housing is molded of peroxidecured EPDM insulating rubber, which provides deadfront safety in a small, hotstick operable unit.
The operation of the VariGAP M.O.V.E. Arrester differs from conventional gapless metal oxide arresters. During steady state conditions, line voltage is shared by both the resistance graded gap structure and metal oxide varistors. When overvoltages occur, the gaps sparkover, leaving only the metal oxide varistors in the circuit. This results in lower discharge voltages than are possible with gapless metal oxide arresters.
The superior protective characteristics of the VariGAP M.O.V.E. Arrester provide excellent protection to underground systems. They are used in pad-mounted transformer and entry cabinets, vaults, switching enclosures and other installations to provide shielded deadfront arrester protection. They are designed for use with 200 A loadbreak interfaces that conform to IEEE Standard 386 to limit overvoltages to acceptable levels, protect equipment and extend cable life.
