td4600 integrated automation testing system for electric power

专用于检测变电站自动化系统,准确度为 0.02 级 / 0.05 级可选

交流采样检测:可进行虚负荷校验 ( 三相标准源 ),或实负荷校验 ( 钳形夹测电流 )



谐波功能:三相电量可加载 ~ 21 次,幅度 / 相位均可调的谐波


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.


 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.
