Medium-voltage voltage sensor MS5200 series

Hall effect

Megger’s MS5200 is a medium voltage sensor with 0.5 % current and voltage measurement accuracy The MS5200 is an on-line wireless system for medium voltage overhead lines, providing on-line information about faults and grid operations. The MS5200 smart grid medium voltage sensor complements distribution management systems by providing on-line information about faults and grid operations. It includes the ability to connect to ground to enable you to perform a direct voltage measurement instead of calculating the voltage from measurement of the electric field. The 0.5 % accuracy of the voltage measurements makes the MS5200 the ideal choice for applications such as Volt/VAR optimisation, medium voltage power metering, and the detection of technical and non-technical losses. The MS5200 is a modular system designed to operate in power grids with solid grounding and any other type of earthing, including Petersen coil compensation. It works by deploying sensors in a radio network, which then automatically create a secured mesh network between themselves. When required, additional routers and sensors automatically and effortlessly connect to the network and report abnormal events such as surges and current/voltage drops. These can be accessed at any time using the MetryView software. The MS5200 is available in two versions: • MS5200-SU: Sensor unit with radio communications. The unit can be connected to MS5000-GS sensor/gateway or to other MS5200/MS5000 sensors units or to MS3010 gateway or routers • MS5200-GS: Sensor unit with integrated cellular gateway
