overview
model td4600, a multi-function apparatus for field testing the automatic system of substation regularly. composed of three-phase source, dc source, three-phase measurement, dc small signal measurement or other functions. the optional accuracy classes are 0.02 and 0.05.
applied to calibrate the ac sampling devices by real load or virtual load in electric power system, and calibrate three-phase apparatuses, dc apparatuses, transmitters and periodic meters. there are other functions as following: accuracy of time calibration, teleindication storm test, teleindication anti-shake test, resolution test for soe, breaker simulation, network performance test, synchrometer calibration, monitoring and recording for protocol.
features
● 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 adjustment methods are supported. the three-phase electrical parameters can be adjusted uniformly or separately.
● synchrometer 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.
