G&W Electric’s sensor technology is based on highly innovative, customizable, high precision low power instrument transformers (LPITs) that can meet the needs of the modern grid. G&W Electric’s voltage sensing technology is a high accuracy, temperature compensated capacitive divider with high frequency measurement bandwidth which enables users to collect critical voltage data for optimizing grid power delivery and reliability. G&W Electric’s current sensing technology utilizes Rogowski coils that can measure a wide range of current measurements with high accuracy, from dynamic system loads to fault currents. Rogowski sensors are safe with no hazardous secondary voltages in the event of an open secondary circuit.
