SPD Reliability Test


Thread Starter


We have installed SPDs in our PLC panel of MTL make tb48. But since this is a critical component of the lightning protection, can someone suggest a method to test the device. There are dedicated SPD testing devices available in the market. But if there is another way out there that would be helpful.
If you mean MTL type TP48? these are intended for use out in the field usually to protect instrumentation exposed to possible storm conditions.

I suppose you could test with a Megger or insulation testing device but unsure what this would achieve.
