Abstract
This course is designed primarily the electrical wiring in a 10KV transformer station Factory ,
which involved the transformer to the cable, the choice of bus bar and cable options, the compensation
of wattless power , relays, the fuze protection. The main problem of the Transformers into the project is
the selection of high-tension cable lines, we choice the different models of electricity which was based
on loading of the district.
With the introduction of several transformers for power supply, the introduction of sub-bus bar,
according to the principles of the average load in two separate generating lines, distributing the loads in
two separate generating line.
Electricity lord connects line is the vital link of transformer substation in
power plant, the draft of the electricity lord connects line relates directly to the choice of the whole
substation's electric equipments, the arrangement of the distribution electricity device, the determination
of the relay protection of power system and the automatic device, It is a decisive factor of the invests
size to the transformer substation electricity part.
We use to the method of complete concentration to compensate the wattless power .For each
line; we have a relay, coupled with fuze protection. The design of the power supply system is a rather
integral design; there are certain reference values to next design.
