MQ579 Multifunctional Three-Phase Power Quality Analyser, when connected to an external Rogowski coil or voltage-type CT, enables non-disconnect testing. This simplifies testing procedures, reduces installation costs, and facilitates engineering testing alongside inspection and maintenance of power distribution systems
u Supports single-phase and three-phase systems, measuring multiple electrical parameters including current, voltage, power factor, power, and energy. Power quality parameters encompass harmonics, unbalance, inrush, droop, and extreme values.
u Beyond measurement capabilities, the MQ579 incorporates various recording functions, including programmable interval measurement logging and waveform recording. An embedded 32 GB memory card stores data and recording functions.
u Standard RJ45 Ethernet and RS485 communication interfaces, compatible with various configuration systems via standard Modbus-TCP and Modbus-RTU protocols, transmit front-end electrical parameters in real time to the system data center
