IEEE/AIEE 87-1961

The provisions of this Recommended Practice apply to the construction and application of controllers for alternating-current motors in the medium-voltage classification (601 to 5,000 volts). Although many of the specifications herein have been influenced by the conditions peculiar to the processing areas of the industries, it is probable that they may be applied to all purchases of controllers for a given company in order to promote uniformity. They are intended as minimum requirements, and should be supplemented where special needs exist

The purpose of this Recommended Practice is to define and recommend specifications for medium-voltage motor controllers for application in the rubber and plastics industries, to promote: a. Safety to personnel and equipment, including the reduction of fire and accident hazards. b. Maximum production with minimum unscheduled shutdowns. c. Reduced maintenance and increased life of equipment. d. Clarification of users' needs and installation conditions, to reduce special engineering and chance of error in specifications. e. Over-all economy. The contents of this publication are intended to bring to the attention of engineers, management, and equipment suppliers the important features necessary to meet the specific requirements of the rubber and plastics industries.
