ZW32 zw20 recloser remote controller unit relaying control terminal
Description
Recloser controls are the front line of the distribution power system, often located on feeders or in distribution substations. Recloser controls supply the intelligence to the network and handle the network protection and in many cases even the RTU functionality. The protective relay senses the faults, assists the vacuum circuit breaker module in an auto recloser to clear the fault on the line.minimize outage duration and the numbers of customers affected by faults.
