We are looking for a solution for contactor failure in a highly contaminated environment. Mercury displacement contactors are not an option. The majority of sealed A/C motor contactors in this category seem to be for the aerospace and military. Highly specialized products for these industries...
A bit? A lot. I am in the process of upgrading and retrofiting the facility, it is unbelievable that this place has not been shut down or someone has not been killed.
I have rectified several dangerous situations and will continue to do so as budget and time permits. This process will take a...
Presto I am must be tired the reading was .4 Ohms if I had an A/C HI-POT I would have found it, just kidding it was my to many years of working on above ground circuitry using ground relay detection and protection were you will never encounter a low megger or Ohm reading from any circuit or load...
There are many things in this facility that are not to code or even industry accepted practices. I am trying to put out one fire at a time. I have not powered this machine back up yet. I was looking for some clarity of what I was seeing. However I belive you have explained what I was seeing. My...
Ok here it goes we have a 3 phase machine that uses 4 three phase motors and one single phase motor. There was a short in the receptacle that caused a phase to ground short after replacing the receptacle, I megged the motors and checked each power phase from the contactor to ground. I had a zero...
