Smart Grid solution for rural networks capable of identifying and locating grid faults

Metrycom’s Rural Networks Smart Grid Solution is based on its novel MetrySense-5000 (MS5000) sensors, which is an integrated overhead line monitoring solution possessing an advanced proprietary and inexpensive radio network capability, specifically designed to operate on medium voltage (MV) networks.

The MS5000 dramatically improves the quality of distribution throughout rural grids, even in their remotest segments.

Unique visibility. Improved results.

MetrySense-5000 is an online wireless monitoring system, which is designed to be integrated in a distribution management systems (DMS) in order to provide online information about faults. The system is designed for solid grounding and also for Petersen coil compensated power distribution grids. Using MetrySense-5000, the maintenance teams can significantly shorten the search of faults in the distribution network, reduce the amount of power interruption events, reduce the damage to the network during the search and improve safety. Metrysense-5000, is extremely efficient in saving costs of energy not supplied.

The Sensors are easily deployed using grip all hot stick or insulated gloves:

Installation using grip-all hot stick

Once deployed, the sensors automatically create a secured mesh network among themselves, and connects to the communication infrastructure of the power utility though a gateway unit. The distance between the sensors is up to 10km, depending on the installation scenario and local radio regulations.

Extremely low power

The sensors charge inductively from average load current as low as 2A. In addition, there is an option to use integrated miniature solar panels that can charge the unit is the load current is too low. In this case the unit automatically and dynamically selects the source of the power feeding (i.e. induction or solar) according to the strongest power supply available.

High endurance batteries are used, which can operate in a range of -30oC-85oC for 10 to 20 years without need of replacement. The units can function for over a week without recharge.

Powerful online fault detection & sensing

Information from the sensor can be displayed using MS-5000 control application or though the utility’s standard GIS system. The sensors measure current with accuracy of 1%, and can sense the level of the voltage by detecting the electric field near the wire.
