I learned the hard way not to vacuum electronics. The air itself passing over the circuits can cause enough static to create issues. So no Vacuum on the market can stop that. In our computer shop we learned to place a vacuum on one side and static free air from a can blowing in its direction. It...
I certinly received more than I expected. I know RTD testers for communications check system impedence not just resistance. Thinking of in those terms simplifies the way I was looking at the test. Certainly makes sense once you put it in Electronic terms rather than electrical. I now understand...
Well all this has been wonderful and i appreciate all your time and knowledge. I noted 2 contradictions that confused the issue even more. IEEE stated that the insulation reading would be higher but the biddle quote stated the reading would be lower. Then again if i am testing and dont like the...
Recently had a boss tell me to look over a procedure. he had us testing using a megger with red and black leads. We are asked to use the red lead to ground and the black lead to the power connection for each phase.
My recommendation was to switch the leads locations so the black was on ground...
We had 3 generators we balanced onboard ship and we never had an issue with neutral current between generators. Once the frequencies were in sync and the load balanced between the generators they fed the load with no problems between them.
In my experience it has been born out of, " We never did it like that before", syndrome.In this case my information has come from someone not doing the test correctly. They hooked up a megger to one end and forgot to unhook the other. Thus frying circuits. On a motor or transformer if you do...
