l Front communication port: 1 RS-232 for testing and setting.
Features
l Remote tripping is supervised by various controlling elements in RCS-925. The relay adopts compensated overvoltage element, compensated undervoltage element, DPFC element, zero sequence current element, negative sequence current element, undercurrent element, low power factor element, low active power element, etc., as local criterion of remote tripping. Those criteria can be enabled or disabled by corresponding logic setting. If anyone of these criteria elements is met, remote tripping command will trip the remote breaker.
l Innovative technology to prevent any undesired trip caused by any component failure is adopted. The relay has two independent data acquisition paths, one for a fault detector and the other for protection and its logic. Tripping outputs are supervised by the fault detector to prevent a mis-operation.
l The connector type can be selected as connectorized wiring connector and crimp terminal connector. The unique connectorized wiring connectors from the relay rear panel to the terminal blocks on the rack or cabinet makes the on-site commissioning and replacement much easier than when you do the commissioning using the traditional screw terminals on the rear panel.
l The relay is compatible with multiple protocols- IEC61850 and IEC 60870-5-103. It provides networking interface such as RS485, RS232 and Ethernet port.
