Product Description
surge protective device tester Introduction
Surge Protective Devices Tester, SPD Tester 888 is designed for on-site testing of Surge Protective Devices (SPD) and the SPD's components. This simple operation allows to measure a wide test range of the Nominal Voltage and Leakage Current. Users can determine the status of these components according to the tester readings through an easy-to-read LCD display.. Precise auto-sensing shutoff and audible function indication to obtain a highly accurate results.
The tester can measure both type of SPD's components :
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 (Solid Discharge Tubes, Gas Discharge Tubes, Spark Gap)
The SPD tester injects an increasing voltage(10V/ms) into the component and measure the Break Down Voltage of the component.
