What sort of 3 phase systems do most ships use? Is it usually a delta or wye style set-up?
Are “High-Leg” or “Hot-leg” systems common in the maritime industry?
All of my seatime was in the Navy where I was an Engineman and forbidden from working on anything electrical on the ship. You can literally go to captains mast for even doing something as simple as using a meter to read voltage if your not an Electricians mate. Its freaking stupid when I had to diagnose a refrigeration issue without being allowed to touch a meter. I use to have to keep a sparky with me and tell him, “ok check that switch… Whats my amp draw on that motor… etc.”.
Anyway, since I’ve been out I have learned the juice side pretty well in the refrigeration and power plant industries and just got approval to test for my electrician endorsement. I understand the civilian world is a little more realistic with letting engineers work on electrical equipment and I just got my first job so I want to have an idea what to expect. Also does anything special have to be done about grounding? Still wondering how thats gonna work on a ship.
