Content introduction

(1) Installation of a properly selected secondary ac surge arrester at the facility main service disconnect provides the best method for ensuring that high energy transients are not coupled to equipment by ac distribution lines within the facility. The surge arrester installed must have certain characteristics to ensure adequate protection. (a) The arrester must be capable of safely dissipating transients of amplitudes and waveforms expected at the facility for a predetermined period of time. Selection of an arrester that will provide protection for a period of ten years is recommended. (b) Have a turn-on time fast enough to ensure that transient energy will not cause damage before the surge arrester turns on and clamps. (50-5000 nanoseconds) (c) Maintain a low enough discharge (clamp) voltage while dissipating transient current to prevent damage to protected equipment. (1.5 times system normal voltage)
