SuperTAPP SG
SuperTAPP SG is the latest realisation of the market-leading SuperTAPP range of AVC relays for transformer and tapchanger management. SuperTAPP SG provides practical options to deliver a Smart Grid approach for distributed generation, network interconnection and reconfiguration, flexible and highly variable loads, and many other scenarios which cause challenges for voltage control.
Key Features:
- Complete voltage control package for Smart Grid
- Basic voltage control for standard applications
- Advanced solutions for distributed generation
- Accommodates reverse power flows, diverse feeder load profiles and variable power factors
- Integrated control panel with real control switches
- Comprehensive SCADA protocols including IEC 61850, DNP3 and IEC 60870
- PC software for management of entire SuperTAPP SG fleet, including settings, tapchanger operation, relay and tapchanger diagnostics and historical data
Key Benefits:
