Rugged design, designed for reliability, bushing monitor for OEMs (Original Equipment Manufacturers) with advance and simple integration features to third party systems/gateways
The Rugged Monitoring BM201 is a compact design, designed for reliability Bushing Monitoring Module that can operate under High voltage substation environments. The BM201 Bushing Monitor combines reliability and user-friendly configuration software. It has two variants, 03 channel and 06 channels, that can monitor 3 and 6 bushing respectively. The system is based on proven Balance Current (Sum of Current) method for measuring Tan Delta (Power Factor - PF), and Capacitance of Condensing Type Bushings.
The BM201 connects to the Bushing Adaptors installed at the Voltage / Test taps of the condensing (Capacitive) type bushing. It measures the leakage current from the three phases and calculates the changes in the TanDelta and Capacitance of the bushings. The measured and calculated values are then sent to the third-party system via Modbus (RTU) protocol using built-in serial (RS-485) port. The BM201 also captures the hourly average of the Tan Delta, Capacitance, Voltage for absolute and rate of change. It has the data integration capability of multiple monitoring platforms. There is a dedicated team of experts available for customizing bushing monitoring solutions to meet specific customer needs.
