CT/PT transformer calibration machine/Measurement and control device accuracy tester
Product overview
KDHG-605A measurement and control device accuracy tester is A high-precision power source and high-precision multi-functional standard table integrated equipment developed by Wuhan Kaidi Zhengda Electric Co., Ltd. to meet customer requirements. The standard source part is based on 1.2G MAC DSP, large-scale FPGA, high-speed and high-precision D/A And a new generation of high-precision standard power source composed of high-fidelity power amplifier. It is suitable for electrical measurement, thermal engineering, remote motion, dispatching and other power departments and enterprises that need measurement, inspection and high-precision standard signal sources, and also suitable for other fields that need high-precision standard signal sources for measurement and inspection. At the same time, the equipment is equipped with 5 switching input and 4 switching output. Can cooperate with customers to complete some remote control, remote letter test work.
KDHG-605A can output power frequency (40Hz~65Hz) frequency, phase and amplitude adjustable high-precision voltage and current, is a very high-precision adjustable voltage and current standard source. The KDHG-605A can output very pure sinusoidal voltage and current with a distortion of less than 0.1% and a typical value of 0.03%. The voltage and current output of the KDHG-605A has a very high output stability, with a typical value of 0.004% RD. Therefore, it is very suitable for use in the workplace that requires high-precision inspection and calibration, such as the measurement department for the detection of various voltage, current, power and other electric parameter meters.
KDHG-605A can also measure three-phase voltage, current, frequency, phase, active power, reactive power, electric energy and other parameters, and can measure waveform distortion and 2~50 harmonics, the upper configuration software integrates more abundant and convenient operation items.
