Overview：

This Tester is used to verify the electrical performance of Zinc Oxide Arrester. The instrument is suitable for various kinds of voltage levels zinc oxide arrester de-energized testing or energized testing thus define the risk and inner insulation moisture and valve aging defects.

Technical parameter:

1.Power supply: support external power adapter (12V/2A) or internal battery

2.Measurement range:

1）Leakage Current Range (peak): 0-10mA (extensible)

2）Voltage range: 30-100V(extensible)

3.Accuracy

1）Current: When total current >100μA ± 2% reading ± 1 digit

2）Voltage: When reference voltage >30V ± 2% reading ± 1 digit

3）Wireless: ± 5% reading ± 1 digit

4.Testing parameters

1）Waveform of Total Leakage Current.

2）RMS and Peak Value of Fundamental Wave

3）RMS of Fundamental Component for Resistive Leakage Current and 3 5 7 times RMS

4）Peak Value of Resistive Leakage Current Component: Ir+ and Ir-

5）Capacitive Current Fundamental Wave Phase angle difference of Total Voltage and Total Current
