The Equipment is a "stowaway" passenger in a free Space in a watertight container. The working environment inside this Space is 6 bar, due to the pressure lines in and out of it. It’s a safety measure due to some reason. We have been granted use of that free Space to my customers test gear that I have to control is working correct by using the four 4486a. It’s a study of temperature, vibration, gas, etc. in technical Equipment. What’s happening is that small currents, builds up, of uncertain reasons and make the readings of the sensors uncertain. The Fluke 8846 measure different values (Current, voltage and capacitance) different places in the POD, umbilical power, string power, battery backup, but also the different Earth/ground differences that comes and goes. Platform runs their own generators, fase problems occur, and makes problems. All this adds up to electrical fen omens that we need to uncover. Problem is, that we need accuracy of the measurements and have no umbilical that we can use for Remote control or reporting up. The equipment goes Down, stay there for days and months. I do this for a student in underwater drilling Technology. We have come to very good conclusions so far, so on track, but accuracy could be better. Later on I’m promised that i can show Pictures and video of some of the work as soon as his doctorate is done and presented.
Sorry about my bad spelling, but spellchecker that was here before is gone.
