How Calculat the Cable Sizing of HT/LT System & Explian by
one Exampal?
Answer Posted / habib
Cable size (sq.mm.) is selected dpendent on 4 facors
1. Current carrying capacity (popularly termed Amapcity)
of the cable.
2. Voltage drop that can be tolerated at the load point.
3. Short circuit tolerance of the cable.
4. Mechanical strength of the cable.
A cable is selected fo the job that can meet all these
criteria.
Basically HT and LT cables are of same material but the
difference is in insulation.
Looks too much like a text book lesson. If you can post
your exact requirement, I would try to help.

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
