IEEE 625-1979

These recommendations apply to all electrical equipment such as substations, power transformers, motor controls, generators, distribution systems, instruments, and storage batteries commonly used in cement plants. They are intended as a guide and may be supplemented where special needs exist.

The purpose of this recommended practice is to define and recommend practices for improving electrical maintenance and safety in the cement industry in order to promote: (1) Safety to personnel and equipment. (2) Maximum reliability with minimum loss of production (3) Reduced maintenance and increased equipment life (4) Clarification of needs and conditions to reduce special engineering and chance of error in specification (5) Overall economy

New IEEE Standard - Superseded. Superseded by 625-1990. Assists in the effective application of relays and other devices for the protection of shunt capacitors used in substations. It covers the protective considerations, along with recommended and alternate methods of protection for the most commonly used capacitor bank configurations. Capacitor bank design trade-offs are also discussed. This guide covers protection of filter tanks and very large EHV capacitor banks, but does not include a discussion of pole-mounted capacitor banks on distribution circuits or application of capacitors connected to rotating apparatus.
