GF302BSMART THREE PHASE TRANSDUCER CALIBRATOR

GF302B portable smart three phase transducer calibrator is suitable for power plant and power grid companies for the following function: measuring and testing department and instrumentation classes, national levels measuring 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, 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. Also 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.
