SPD 888 Tester
Surge Protective Devices Tester, SPD 888 Tester is designed for on-site testing of Surge Protective Devices (SPD). It allow to measures both the Nominal Voltage and Leakage Current of different SPDs according to IEC, IEEE, ANSI standards.
The tester can measure both type of main component inside SPDs, including:
a) Voltage Limiting Type (MOV, TVS, Zener Diode ) The SPD tester injects a constant current into the component and measure the Let-Through Voltage. Then, the tester can use this voltage to find out the leakage current of the component.
b) Voltage Switching Type (Gas Discharge Tube, Solid Discharge Tube, Spark Gap) The SPD tester injects a constant current into the component and measure the Break Down Voltage of the component. What the tester outputs is slope of 10V/ms voltage not a constant current.
