The DRMCC system provides Dynamic Rating,
Monitoring Control and Communications
for Power Transformers.
The DRMCC-T3 is a highly modular, low cost, microprocessor based monitoring and control system for power transformers. Because of its modularity there are many optional features and functions available. Each system can be different, being customised to the requirements of a particular installation.
The DRMCC-T3 can be fitted to new transformers in the factory or retrofitted to existing transformers in the field provided that the required auxiliary equipment is fitted. Each DRMCC can monitor and control one transformer.
Typically a DRMCC has an Interface Unit (IU), a Control Unit (CU) and optional additional equipment as required for the application. The CU needs to be fitted in a weatherproof cubicle at the transformer. The IU may be local (in the same cubicle) or remote (typically in a control room) or there may be two IUs, one local and one remote. If there is a substation control computer an IU may not be required. Both IU and CU are highly configurable.
The DRMCC is an Integrated microprocessor-based system with:
- Dynamic Rating - real time thermal limit predictive loading capacity-real time aging
- Monitoring - data acquisition & storage of all data for the entire transformer
- Operating data: volts, amps, watts, vars, tap position, temperatures - ambient, oil and winding hot spot, etc
- Condition monitoring probes - DGA, water in oil, bushing and OLTC condition
- Control – Voltage (OLTC) and Cooling
- Communication –Web server(at sub or LAN / WAN), IU, SCADA, modem, TCP/IP, DNP 3.0, Modbus
