Utilizes a state-of-the-art 32-bit DSP processor, this power quality monitoring device integrates high-speed sampling, computation, analysis, statistics, communication, and display functionalities.
Installable in low-voltage incoming line cabinets, switch cabinets, or photovoltaic grid-connection cabinets, this system enhances the intelligence of complete switchgear, enabling real-time online monitoring and control of various electrical parameters in the power system. Our online power quality monitoring device is a new-generation embedded touch screen product developed and designed by our company. It features circuit breaker opening and closing, position, energy storage, under-voltage, and trip switch quantity detection. It can monitor power grid harmonic content rates up to 2-51 times, total harmonic distortion, three-phase voltage imbalance, flicker, voltage deviation, voltage fluctuation, frequency, active and reactive power of various harmonics, power factor, and positive and negative sequence, among other power quality indicators. It also has MODBUS (RS485) communication capabilities for remote control of circuit breaker operations. The entire software is programmed in advanced languages, ensuring high system reliability.
