Explain the laying procedure and laying depth of submarine
cables under sea?
Answer / abhinav
An underwater electric power cable which has a minimum
radius of curvature to which it can be bent without damage
and which can be suspended between underwater suspension
points in no greater than a predetermined length for a
desired service life is layed by first laying a flexible
steel rope along the desired underwater course and
adjusting the rope position and length so that there are no
curvatures thereof less than the minimum radius and no
lengths thereof greater than the predetermined length, and
then, the cable is layed alongside the rope so as to follow
the configuration of the rope.
burial depth can be 5 metres for 132 kv .

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.
Can we connect two or more energy meters/Amp meters on one CT set(Three phase).
