Remote Feeder Monitoring System

The Substation Total Demand Monitor has been designed to provide an easy to install (30-45 minutes), versatile and configurable metrology system. The total demand of the substation is calculated by the summation of the feeder loads and all loading parameters are measured. The system may be configured to measure transformer output and feeders by using Rogowski coils. Busbar voltage phase to phase angles may also be measured for the 3 phases.
Working in conjunction with RTU, which provides RS485 over Modbus; the data is transmitted to a central server over GPRS using DNP3NEXUS protocol. This can also be made available to other manufacturer�s host servers if required. Continual logging of metrology values is done via the Modbus interface and all logs are datetime stamped, with the clock being synchronized with central server. Alarms and alerts relating to a range of measured parameters can be sent out.
