Power line monitoring and analysis of faults in Distribution lines

Description

Smart Grid medium voltage sensor MS5000 for overhead line networks  from 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 METRYSENSE5000 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.

MS5000 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 .MS5000 is modular: Once sensors are deployed in a radio network, they automatically create a secured mesh network among themselves. When required, additional routers and sensors automatically and effortlessly connect to the network. The sensors report abnormal events such as surges and current/voltage drops and can be accessed at any time by the MetryView software.

Grid Analytics Solutions consists of

1.MS5000-On line wireless monitoring system 

MS5000 is an online wireless system for overhead distribution and sub-transmission lines that complements distribution management systems (DMS) and provides online 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 of doing so in the field.

2.Gateway/router integrates with MS5000

MetrySense 3010 is a gateway/router that integrates with MetrySense 5000 sensors, allowing radio-mesh networks in locations with limited cellular coverage. The MS3010-RU, on the other hand, is a router unit that can extend the coverage of the mesh-radio network and can also interface with the utility communication infrastructure.

3.MetryView software-Server and software combination for collecting and analysing data 

The MetryView server and software combination performs two-way communications between deployed sensors and RTUs in the field, It then, analyses the data that has been collected and partially analysed by the sensors, and visualises the results with a diagram on the screen which can be interacted with using an intuitive user interface.
