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.

 

Application

Advantages

1. Fault clearance functionality and RTU functionality.

2. Status monitoring – local and remote.

3. Configuration and Control – local and remote (complete).

4. Power quality monitoring – local and remote.

5. Event recorder for fault analysis.

6. Metering – local and remote.

7. Multi signalling protocol - IEC 870-5-101, IEC 870-5-104,IEC 61850 and IEC 60870-5-101 and DNP.

8. The operator panel module which provides the Human Machine Interface.
