td4500 calibrator for ac sampling and transmitters -凯发k8国际

overview

model td4500, a multi-function apparatus for calibrating electrical power apparatuses and electrical measuring apparatuses. composed of three-phase source, dc source, three-phase measurement, dc small signal measurement or other functions. the optional accuracy classes are 0.05 and 0.02.

applied to calibrate the ac sampling devices by real load or virtual load in electric power system, and calibrate the three-phase apparatuses, dc apparatuses, 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 2^nd to 21^st 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.

● 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.
