Please tell where did you use the cable. i.e. for control
and power purpose.

a/c to formula you can calculate the cable size.

LT purpose :- 1 sqmm al cable :- it will take 1.5 amp
current a/c to formula you can calculate the cable size.

HT pupose :- we can go a/c the LT purpose cables but there
is voltage drop plays very crucial role, first calculate
the current value then calculate the voltage drop after
doing these exercises you can select the cables.

Just a silly question but just to make my curious mind bac to normal - Why was not 67 and 67N relays built into a single relay as i have noticed that the R,Y,B CT wiring end up into the 67 relay while the common of the R,Y,B CT wiring end up into the 67N relay. Then it was better if a single relay was manufactured just like the distance relay (21). Another question i would like to ask is - how do we know where the 67 and 67 N relay has to be placed.why is it not placed at the transformer bay? In the substaion that i am working -i have noticed that it is placed between a breaker and a common double bus bar and this line bay is connected to another substation at a remote place which is furthur connected to a load.
