Evaluating your electrical distribution system and modernizing with vacuum technology

A majority of the operating cement plants today have medium voltage electrical switching equipment in use which was built in the 1960s and 1970s. Because of plant expansions or to increase reliability and reduce maintenance cost, it may be time to review the remaining life and application of the existing equipment. In order to simplify the decision making process, this paper establishes the basic analysis of evaluating an electrical distribution system and consideration of using vacuum retrofit in existing medium voltage switchgear. The continued demand for vacuum interrupters relates to their successful field experiences, increased confidence in reliability, cost effectiveness and simplicity of the installation.
