Automatic Moa Metal Oxide Arrester Lightning surge Test System
General information
SXYZ-IV Metal Oxide Arrester Tester is a preventive on-line/on-site
test tool to check the health of Metal Oxide Arresters of different
voltage levels. It can detect dangerous problems inside the
arresters such as insulation moisture and valve plate aging.
Features
√ Large LCD screen, English interface, easy to operate.
√ Measurement process is controlled by SCM, MOA's measuring
including: full current, resistive current and harmonic, power
frequency reference voltage and harmonic, active power and phase
difference, the current and voltage true waveform to be displayed
in LCD screen.
√ High precision sampling and processing, advanced Fourier harmonic
analysis technology, to ensure the test data be more reliable.
Fundamental harmonica and 3~7 times' harmonic content could be
analyzed accurately.
√ High speed magnetic isolating sensor to sample the input voltage
and current signal directly, and guarantee the reliability and
security of data.
√ PT secondary wire connection could be instead by electric
inducting or wireless transmitting.
√ Resistive current could be measured directly without connecting
PT secondary.
√ Six test ways is more convenient for the user.
√ Three phases measuring simultaneously and auto compensated.
√ Designed with resistive current fundamental harmonic peak value
output and side phase calibrating functions.
√ Build-in high speed printer, and rechargeable battery.
√ 120 groups data storage.
