GF302B Three Phase Ac/Dc Power & Transducer Calibrator
GF302B portable three phase transducer calibrator is suitable for power plant and power grid companies for the following function: metrology and testing department and instrumentation classes, national levels metrological and testing institutions, railway, petroleum, chemical industry and other large industrial and mining enterprises, scientific research units, etc. The core technology function with 32bit digital signal processor (DSP+MCU) and 24 high-speed digital A/D converters composed of high precision work frequency communication terminal. It can test the basic error of power transducer - (voltage transducer, current transducer, power factor transducer, frequency transducer, active & reactive transducer, DC transducer etc), the change caused by the influence of voltage, current, waveform, power factor, etc., and the ripple content and response time in the output DC voltage (current) of the transducer. It can also as Power calibrator, check power meter error, and as standard three phase ac voltage source and current source, or as DC power source. It is one ideal high precision calibrator in electrical laboratory.
