1.8/20μS(150kA)impulse testing device

For SPD impulse current capacity test, mainly applied for MOV(a basic element of SPD)selection, routine test and destruction test for SPD product performance.

2.2mS(500A)impulse testing device

For SPD energy level test, mainly applied for MOV quality test, and SPD useful life estimation.

3.Constant temperature & humidity AC testing oven

Applied for MOV aging and screen experiment, SPD products aging experiment and inspection.

4.AC/DC online impulse testing device

It simulates actual operational state, conducts online lightning strike experiment, tests SPD protective performance.

5.AC/DC voltage tolerance testing device

Applied for estimating the maximum constant operating voltage and actual useful life of SPD

6.Fuse (thermal stability) testing device

Applied for SPD thermal stability test, make sure that SPD would be disengaged from the power system safely in case of MOV failure, it is a very important function for the device safety in utilization.
