Product Description
SPD 888 portable surge protectiv device tester is designed for outdoor testing of Surge Protective Devices (SPDs). Users can determine the status of these components according to the tester readings.
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 current of 1mA into the component and measure the Nominal 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 increasing voltage(10V/ms) into the component and measure the Break Down Voltage of the component.
