Best operating results are achieved when reclosers are protected with surge arresters. On line applications, arrester protection is recommended on both sides of a recloser. If protection is to be provided on one side only, it should be on the source side. In substations, arresters should be located on the load side.
Cooper Power Systems distributionclass surge arresters provide excellent protection.
Applications
The Nu-Lec Industries automatic circuit reclosers provide many outstanding advantages to the user. New and innovative features have been made possible by the intimate way the pole mounted circuit breaker and control cubicle work together.
WSOS is the Nu-Lec Industries Switchgear Operating System software based on Microsoft Windows®. It provides easy access to all switchgear functions from opening/closing, through configuring protection and communication parameters to accessing measurement and analytical data. By using a desktop or portable PC engineers can manage a large number of reclosers either remotely via a communications link or locally via a serial port or Ethernet connection.
