Fault detection Metering & monitoringCommunicationsSoftware

  Fault Detection
Effective fault isolation is a key feature for grid reliability. The Multilin DGCM provides early warning for downstream overcurrent and earth faults. It can be programmed to isolate a faulted segment, either independently or from the remote. The Multilin DGCM also offers control, monitoring and diagnostics in one integrated, efficient design.

Overcurrent Protection
Instantaneous and time overcurrent functions are available for phase, neutral and negative sequence currents. A variety of time curves are provided, including IEEE/ANSI, IEC A/B/C/long time inverse/short time inverse, definite time and user-programmable curves.

Cold Load Pickup
The Multilin DGCM can be programmed to block instantaneous overcurrent elements, and raise the pickup time of overcurrent elements, when a cold load condition is detected. The cold load condition is detected during the closing of the breaker on a feeder that has been de-energized for a long time. The feeder inrush and motor accelerating currents during breaker closing may be above some overcurrent protection settings.

Overvoltage (OV) Detection
The phase OV protection guards voltage sensitive feeder loads and circuits against sustained OV conditions. It generates alarms when the voltage exceeds the selected voltage level for the specified time delay.

Undervoltage (UV) Detection
The phase UV detection alerts utilities against sustained UV conditions. The UV detector generates an alarm when the voltage drops below the selected voltage level after a specified time delay.

Power Loss
The Multilin DGCM can detect a power loss condition in each phase of the power distribution line. Open/close commands are blocked, unless currents and voltages of each phase fall below minimum set values.
