We must consider numerous factors to calculate the exact
safe size of the cables for a particular load.
Please let us know whether the cable is to be laid in
ground or it will be overhead or any other way.
Secondly, you want an aluminium cable or copper cable?
Thirdly, the load is single phase or 3-phase?
Moreover, the motor is induction motor or any other type?
because we have to consider harmonics also.
For e.g for a 3-phase load of 80kw, the aluminium cable to
be laid inside the ground must be 150 sq.mm for perfectly
At a family reunion were the following people: one
grandfather, one grandmother, two fathers, two mothers,
four children, three grandchildren, one brother, two
sisters, two sons, two daughters, one father-in-law, one
mother-in-law, and one daughter-in-law. But not as many
people attended as it sounds. How many were there ?
Hello, I am just preparing my self for a university interview and struck on the 11kv ring main unit system network. I just know that ring main unit has total three breakers, fuses and use to supply a power to any load/ building without any interrupt. But i am not be able to visualize the connections, either Ring main unit getting power from two different power sources? or there is always one feeder in complete ring circuit??? I would be highly thanks full of you help me.
what is the Mechanism of energy saver FAN how average
power,reactive power, power factor e.t.c realated to it and
how it apply to this FAN .and how this fan save energy
w.r.t circuit analysis,plz repaly to this question this is
the assignment to given to me.thanks
