Power lines insulation monitoring system MetrySense-4000

The company Soyuztekhenergo (OPTEN Group of companies) has completed the installation of the MetrySense-4000 power lines insulation monitoring system for JSC Lenenergo. The system includes four sensors that monitor the insulation condition of two power lines, as well as two gateways installed in two substations for transmission of these data. The system has been launched and is operating normally. 

MetrySense-4000 is a wireless sensor solution for monitoring transmission and distribution power lines. Unique partial discharge sensors are used to detect contamination over power line insulator stings. The system provides real-time information to maintenance teams, helping them reduce operation costs and improve the power quality of the grid. 

The system provides an online view of the contamination level of the power lines. This means maintenance teams focus on washing the right sections of the transmission line at the optimal time, reducing washing costs, and improving power quality by reducing the number of flashovers and power sags. 

Benefits:
Х Provides online grid visibility. Introduces real time high-voltage grid visibility of partial discharges along the lines and in substations.
Х Predicts flashovers. Reduces interruptions and outages.
Х Reduces maintenance costs by washing insulators at the right segments of the power line and at the optimal time.
Х Provides feedback on the quality of insulator washing operations.
Х Provides infrastructure to additional sensor solutions by including generic interfaces to many types of sensors.
