The Metravi PRO PA-900 3-Phase Power Quality & Harmonics Analyser, when externally connected with open type Rogowski coils or voltage type CTs, is capable of non-destructive wire testing with simplified test steps. It helps save construction costs, and is more convenient for engineering tests as well as aids in the inspection and maintenance of distribution systems.

Features of the Metravi PRO PA-900 3-Phase Power Quality & Harmonics Analyser:

• Supports single-phase and three-phase systems.
• 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.
• In addition to the measurement function, the PA-900 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.
• With standard configuration of RJ45 Ethernet communication interface, through standard Modbus TCP protocol, it is compatible with various configuration
  systems and can transmit the electrical parameters collected by the front end to the system data center in real time.
