SXYZ-II Metal Oxide Arrester (MOA) 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. It’s applied for energized or non-energized MOA detecting of all the voltage levels.

♦   Large LCD screen, English interface, easy to operate.

♦   High precision sampling and processing, advanced Fourier harmonic analysis technology, to ensure the test data be more reliable.

♦   High speed magnetic isolating sensor to sample the input voltage and current signal directly, and guarantee the reliability and security of data.

♦   Continuous testing, the voltage and current curve could be displayed, the test data and curve could be printed out.

♦   The anti-interference calculation is available, to compensate the current deviation of A and C phase against B.

♦   High speed sampling frequency, advanced digital signal processing technology, high anti-interference ability and precision.

♦   Build-in high speed printer

♦   Engineering plastics carrycase, dustproof, warterproof and corrosion prevention, it’s light and portable.
