Innovative – Collaboration

GridKey is a collaboration between Lucy Electric, a leader in medium voltage and low voltage, secondary power distribution solutions, and Sentec, the smart grid and metering specialists.

The experience of both companies is being utilised to continually develop and market an award-winning low voltage (LV) substation monitoring system.

GridKey is a Medium and Low Voltage (MV/LV) substation monitoring system that can be fitted to the feeders of a substation without interrupting supply to customers. It provides continuous remote monitoring of the substations as well as timely warnings, status and loading information.

As a result Electrical Utilities/Distribution Network Operators (DNOs) experience reduced network maintenance costs and significantly increased knowledge of the state of their MV/LV grid.
