overview
model td4510, a multi-function calibrator for electric power apparatuses. composed of three-phase and dc source, three-phase electrical parameters and dc signal measurement, electric energy measurement or other functions. the optional accuracy classes of three-phase power are 0.02 and 0.05.
applied to calibrate the ac sampling devices by real load or virtual load, and three-phase / dc apparatuses, ac electric energy meters, transmitters and synchrometers.
meet the requirements of q/gdw 1899-2013 verification regulation calibration specification of ac sampling electrical measuring equipment. (tunkia is involved in drafting)
applications
features
● ac sampling calibration: the virtual load calibration method is using by three-phase source, and the real load calibration method is using by measuring current with the clamp online.
● transmitters measurement: measure the basic error, dc ripple and the response time for the transmitters.
● harmonic output: the output can load 2nd to 21st standard harmonics with adjustable amplitude and phase to test harmonic influence on the checked meters.
● value adjustment method: fixed-point, rotary encoder, step and potentiometer (option).
● phasor diagram: freely adjust the phase between the three-phase electrical parameters, and intuitively display by phasor diagram.
● excellent human-computer interaction: large lcd touch screen display, touch and button operation modes, easy for users to measure manually.
● electric energy calibration (option): calibrate a single ac electric energy meter by the standard pulse i/o interface.
● periodic meters calibration (option): the fourth voltage output can calibrate the difference of amplitude, phase and frequency for periodic meters.
● proprietary software (option): support the calibration for the checked meters by semi-automatic or full-automatic, data management and report export.
