Microprocessor-Based Recloser Control: New Technology Distribution System Protection Capability

Computer control and automated operation of electric utility systems have so far consisted of relatively large, complex control systems for substations and central dispatch centers. Full utilization of these control capabilities at the distribution level and complete automation of the distribution system will also require more sophisticated controls on the individual devices of the distribution system for both the substation and the distribution line itself. Microprocessors available at present allow the design of the controls needed to accomplish this.
