It is the Relay that can perform protection operation on two distribution networks at the same time. It is equipped with one or more circuit breaker, and then it will be installed on equipment. The 100DR DOCR is not used alone, but is installed together with the C100DR Controller and operated for onsite operation and control, indicating the equipment status, and providing separate RTU and interface.
Input power: DC 24V
Phase and ground overcurrent protection for two circuits
Fault indicator and fault reset button for each phase
4 * 20 LCD and four menu keys
Select operation (Enable/Disable) of protection elements
Support protection curves, TCC: IEC NI, EI, VI
One RS 232 port for Maintenance and RS 485 port for SCADA System
The operation program to check setting, status, and history data
Store the number of trips for each phase on each circuit.
Store total of 2,048 sequential events
Store fault current waves
Systems structured to perform protection operations for two distribution networks using one relay.
Systems using the equipment such as RMU for underground distribution networks to prevents faults on loads from spreading to lines
By performing protection for 2 distribution networks using 1 Relay, the purchase cost of equipment can be reduced.
By preventing faults on load sides from spreading to trunk lines, outage time and sections are reduced
