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#65289;Leakage Current Range (peak): 0-10mA (extensible)

2#65289;Voltage range: 30-100V(extensible)


1#65289;Current: When total current >100#956;A ± 2% reading ± 1 digit

2#65289;Voltage: When reference voltage >30V ± 2% reading ± 1 digit

3#65289;Wireless: ± 5% reading ± 1 digit

4.Testing parameters

1#65289;Waveform of Total Leakage Current.

2#65289;RMS and Peak Value of Fundamental Wave

3#65289;RMS of Fundamental Component for Resistive Leakage Current and 3 5 7 times RMS

4#65289;Peak Value of Resistive Leakage Current Component: Ir+ and Ir-

5#65289;Capacitive Current Fundamental Wave Phase angle difference of Total Voltage and Total Current

6#65289;PT Voltage RMS

7#65289;Power Consumption of Arrester

5.Sampling Method of Reference Voltage Signal

1#65289;Sync with cable: 40 meters (can be extended)
