简介
GDBL2801 MOA tester is a dedicated instrument for detecting electrical properties of zinc oxide surge arresters, the instrument is suitable for a variety of voltage levels of MOA detection live or power outage, which detect moisture inside the device and valve insulation aging and other dangerous defects.
GDBL2801 MOA tester simple, easy to use, measuring the entire process controlled by the MCU, measurable MOA full current, resistive current and its harmonics, frequency and its harmonics reference voltage, active power and phase, largescreen displays real voltage and current waveforms. Instrument using digital waveform analysis technology, harmonic analysis and digital filtering software such interference method enables accurate measurement, stable and accurate analysis of the content of the fundamental and harmonic 3 to 7 times, and overcome interference and white, right phase measurement edge arrester resistive current. The machine is equipped with high-speed printer panel, rechargeable batteries, testing personnel in the field is very convenient. The instrument uses a unique high-speed magnetic isolation digital sensor directly capture voltage and current signals input to ensure the reliability and security of data.
GDBL2801 MOA tester PT secondary voltage as the reference input signal, the input current signal MOA, can be obtained through the Fourier transform of the fundamental voltage U1, Ix1p current fundamental peak voltage and current angle Φ. Therefore phase with the voltage resistive electrical component, fundamental wave peak flow (Ir1p), quadrature component is the capacitive current fundamental peak (Ic1p): Ir1p = Ix1pCOSΦ Ic1p = Ix1pSINΦ taking into account δ = 90 ° -Φ equivalent dielectric loss angle Φ directly evaluate the MOA is very simple: there is no "white interference", Φ mostly between 81 ° ~ 86 °.
Cx: capacitance. Calculated as follows:
Cx = Ic1 / 2πfU1
Ic1 capacitive current RMS, U1 is the fundamental RMS voltage, f is the frequency of the grid.
3.5Kg (without cable)
Working environment: temperature: -10-50 ℃ Humidity: <90%
