Product Description
GF302D Portable Three-phase kWh Meter Test Equipment Accuracy class 0.05/0.1 Application The test equipment is used for grid corporation of measurement and test center, management department of power supply bureau, national energy measurement of testing authorities, and also used to test each kind of single/three phase kWh meter of industries and mining enterprises as well as electric meter manufacturers. Meanwhile, the equipment also can be used as one high standard power source. Introduction The device is according to nation verification regulation JJG597-2005 "AC electric energy meter verification device" and the relevant countries standard requirements and design three-phase 0.05 magnitude table source integration calibration device. The core technology of the function of device with digital signal processor (DSP) and 16bit high-speed digital converter composed of high precision work frequency communication terminal; The signal source of use is DSP and 16bit high-speed digital-to-analog converters can control of the sine wave, distortion wave signal source; Equipment has high precision, stable and reliable, and convenient operation, flexible, and other characteristics; Is the electric power system used for verification of electric energy meter an ideal equipment. Main Functions and Features To test three-phase electronic, mechanical kWh meter error; To check three pieces of different constants of kWh meter error; To check multi-function kWh meter time, demand cycle error; Built-in electric verification procedures, automatic or semi-automatic for verification, saving 1000 group checking data; It can be used as voltage source, current source and power source for high precision and high stability standard resource; Display in big 6.4 inch color screen; It is calibrated in the software , not open the case, very stable and reliable; With short circuit, current output terminal and the output voltage open protection and power amplifier overheating protection function; Automatically failure detection function, shows fault part, the convenience users check line; With USB and RS232 interface, and computer connection for data management.
