This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...

Dielectrics (insulating materials for example) when subjected to a varying electric field, will have some energy loss.   The varying electric field causes...

I was having a conversation the other day about voltage levels.  While everyone was in agreement that low voltage was 1000 V and less, there was more confusion...
