GridKey is a family of substation monitoring systems that can be fitted to the feeders of a low voltage or medium voltage substation, typically without interrupting supply to customers. It provides continuous remote monitoring of substations, as well as timely warnings, status and loading information. As a result, electrical utilities/distribution network operators experience reduced network maintenance costs and better understand the state of their LV and MV grids.
Data Centre
Collecting raw data and analysing it to create ‘actionable information’ is key to extracting value from data collected by the GridKey systems. An analysis of available systems against our requirements resulted in the decision to develop a bespoke system, enabling us to incorporate useful features and manage cyber security aspects.
Metrology and Communications Unit (MCU)
GridKey’s MCU318 communicates directly with the cloud-based GridKey Data Centre, which stores and analyses data to provide actionable information.
Cable Smart
The Cable Smart system provides a continuous regime of monitoring to determine the safety of private and public electrical networks. The system consists of two elements, a GridKey MCU LV monitoring device which is installed in a feeder pillar and measures voltage and current and the Autoloop devices which are typically mounted at the end of each of these circuits. The MCU and Autoloop both have an embedded GSM modem which communicates securely with a cloud based data centre where data is collected and analysed to provide an automated electrical safety report and also other analytics on the electrical network.
