1. Product description

Mi550 handheld three phase power quality analyzer, externally connected with open type Rogowski coil or voltage type CT, it can realize none dismantling wire test, simplify test steps, save construction cost, and is more convenient for engineering test as well as the inspection and maintenance of distribution system.

1. Support systems of single-phase and three-phase. It can measure multiple electrical parameters such as current, voltage, power factor, power, energy, and power quality parameters including harmonic, unbalance degree, voltage swell and voltage dip, etc.
2. In addition to the measurement function, Mi550 is equipped with various records, such as waveform records and programmable interval measurement value records. To store and record data, it is internally embedded 32 GB memory card.
3. With standard configuration of RJ45 Ethernet communication interface, through standard Modbus TCP protocol, it is compatible with various configuration systems and could transmit the electrical parameters collected by the front end to the system data center in real time.
