China High Quality Meter test kit Manufacturer – GDYB-D24 Single Phase Energy Meter Test System – HV Hipot

Technical Specification

● Reasonable design and beautiful appearance. The device hanging table frame and the table body frame are all made of special aluminum alloy materials, and the table top is made of fire-proof and heat-resistant fiber materials. The whole device has soft colors, coordinated proportions, and reliable structure. Exquisite craftsmanship, beautiful appearance.
● Dedicated keyboard operation and PC operation coexist, easy to use. This device is equipped with a keyboard, the keyboard comes with a liquid crystal display, and the working status of the device is clear at a glance. The operation is easy and free. The PC control software has clear levels, beautiful interface, and flexible and convenient use.
● High degree of automation. When verifying the electric energy meter, only need to manually participate in the watch, adjust the photoelectric sampler, and correctly design the parameters of the meter, all the verification items (including preheating, creep test, start-up test, standard deviation determination, and basic error determination) ) It is automatically controlled by the PC and completed at one time. The calibration procedure can be in accordance with national regulations or can be customized by the user.
● The photoelectric sampler can realize three-dimensional adjustment, and can sample the turntable signal of the rotary electric energy meter. It can also receive the stroboscopic signal of the electronic energy meter.
● The error processing system can receive the photoelectric sampler signal, the output pulse of the mounted electronic meter and the high-frequency pulse signal of the standard electric energy meter.
● Energy meters of the same type (same rated voltage and calibration current) and different constants can be calibrated at the same time (limited to two constants).
● It can automatically locate the black mark of the turntable of the rotary electric energy meter, which is convenient for diving (starting) testing.
● 2 to 21 harmonics can be superimposed on the power frequency fundamental wave, and the amplitude and phase of the harmonics can be set as required. It can also perform harmonic analysis on the output and draw the waveform.
● The device has high stability, good reliability and large output power. The voltage (current) loop can carry loads of any nature.
● Complete fault detection, location, protection and alarm functions to avoid damage to the device due to man-made wiring or operation errors.
● The PC management software also has functions such as complete report printing, mathematical statistics and asset maintenance.
