IEEE Std. C62.11^TM-2005 IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits (>1 kV)

Revision of IEEE Std C62.11-1999
This standard applies to metal-oxide surge arresters designed to repeatedly limit the voltage surges on 48 Hz to 62 Hz power circuits (>1000 V) by passing surge discharge current and automatically limiting the flow of system power current. This standard applies to devices for separate mounting and to those supplied integrally with other equipment. The tests demonstrate that an arrester can survive the rigors of reasonable environmental conditions and system phenomena, while, at the same time, protect equipment and/or the system from damaging overvoltages caused by lightning, switching, and other undesirable surges.

IEEE Std C62.21^TM-2003 IEEE Guide for the Application of Surge Voltage Protective Equipment on AC Rotating Machinery 1000 Volts and Greater

This guide covers the application of surge voltage protective equipment to AC rotating machines rated 1000 volts and greater. The guide does not cover motors applied in solid-state switched adjustable speed drives. Part 1 covers the insulation surge withstand strength of motors and generators with windings having form-wound multi-turn coils and the application of surge protection to form-wound multi-turn coil motors. Part 2 will cover application of surge protection to generators with form-wound multi-turn coils, plus insulation surge withstand strength and surge protection of single-turn coil generators and motors. Project purpose: This guide is intended to aid engineers at all levels of surge protection knowledge in deciding whether particular machines should have surge protection. The guide may be used in estimating the surge withstand capability and switching surge exposure of ac rotating machinery in usual, not extreme exposure, installations. The manufacturer should be contacted for specific insulation surge voltage withstand values for machinery of particular interest or importance. For those machines, which should be protected, the purpose is to provide guidance in selecting and applying the protective devices. A simple look-up method using tables and a graph is provided for quick estimation of surge rise times and surge voltage levels, and for general use where accuracies in the order of 10% to 15% are acceptable. This method is based on single-phase analysis, neglecting the influence of ground mode surge propagation. A more complex method is provided by formulas to model the three-phase and ground mode propagation. The formulas can be used with calculators or personal computers.
