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 to be used as a guide and may be supplemented where special needs exist. This document is a companion document to IEEE Std 277-1994, IEEE Recommended Practice for Cement Plant Power Distribution [B1] and IEEE Std 499-1997, IEEE Recommended Practice for Cement Plant Electric Drives and Related Equipment [B3]1. The purpose of these recommended practices are to define and recommend practices for improving electrical maintenance and safety in the cement industry in order to promote the following: a) Safety to personnel and equipment b) Maximum equipment reliability with minimum loss of production c) Reduced unscheduled maintenance and increased equipment life d) Clarification of needs and conditions to reduce special engineering and chance of error in specification e) Overall economy Revision Standard - Inactive-Withdrawn. These recommended practices are intended as a reference document for use by members of cement industry electrical maintenance departments. The procedures necessary for an efficient maintenance operation are summarized, and detailed information on maintenance procedures for many of the electrical devices more commonly found in the cement industry is provided.
