The MS5000 (Metrysense5000) Smart Grid medium voltage sensor for overhead line networks (4 to 140 kV) provides real-time grid information, giving you unprecedented visibility of your distribution grids through the accurate identification of high impedance faults and predictive analytics for deteriorating network components. It has been designed for FLISR (fault location, isolation, and service restoration), grid analytics, power quality, and flow monitoring. The MS5000 is an on-line wireless system for medium voltage overhead lines, which complements distribution management systems (DMS) and provides on-line information about faults and grid operations. It uses proprietary hardware and algorithms to support low power consumption while ensuring the high stability needed for large radio networks. The radio system was purposely designed to successfully operate in the harsh conditions of power lines and has a proven record in the field. The instrument uses power harvesting from the line in combination with backup batteries that power the system for up to 3 years in the event of grid failure or switching. It also provides real-time information on faulty circuit, fault type, and location, and it enables maintenance teams to reduce the outage duration by providing accurate fault location in real-time, and consequently reduces SAIDI and CAIDI. The system works with various grounding methods, including solidly earthed systems, impedance grounding, floating neutral, single wire earth return, and compensated/Peterson Coil systems. The system is modular.
