1]how the voltages and frequency are achieved on ships.
2]how does the line and phase voltages are related on ships.
Answer Posted / suseendran
1. Yes ships do have generators. Using AVR's and controlling
prime movers speed, voltage and frequency are achieved.
2. Only one difference b/w our system and those in Ships is
they have unearthed system. Here phase voltage is the
voltage b/w phase and neutral OR earth. Since ships are
unearthed phase voltage is b/w phase and neutral.

HOW TO TEST A LIGHTENING ARREST ER ?
what is saturation kit?which use above 15 kw motors panel side.
If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
