System Combines Sensors with Wireless Communications

The new GridSync combines sensors and wireless communications, allowing utilities to increase grid visibility and efficiency through Volt Var Optimization (VVO).

GridSync, offered by ABB, provides high accuracy current, voltage and frequency information in real time for smart grid applications including Volt Var Control (VVC), demand response, and load monitoring.

The system uses the CVC-110ER extended-range combination current and voltage instrument transformer to obtain highly accurate current and voltage readings from distribution feeders. This real-time data is fed into GridSync’s remote terminal unit (RTU) and then sent wirelessly to the utility for analysis, action, and integration into their distribution management system (DMS).
