As a VNITian, you guys might have observed that VNIT stands out from Nagpur city when it comes to power cut. Power cuts are rare and even when there is a power failure due to some fault we have supply for our mess and in exam time in our hostel even. Wouldn t it be interesting to know how the electrical distribution and substations our college are configured meets the demand of uninterrupted supply? Let s find out!

VNIT receives a special treatment when it comes to power supply, thanks to our director who presented our college as a research ....etc

Now days the electrical power demand is increasing very rapidly. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. These power generating stations< may be hydro electric, thermal or atomic. Depending upon the availability of resources these stations are constructed different places. These places may not be nearer to load centers where the actual consumption of power takes place. So it is necessary to transmit these huge power blocks from generating station to their load c ....etc

Equipment in a substation can broadly be categorized as follows:

structures;

power transformers;

bus-bars;

circuit breakers (33 kV and 11 kV);

isolators or isolating switches (33 kV and 11 kV);

earthing switches;

insulators;

power and control cables;

control panel;

lightning protection surge arrestors;

instrument transformers (current and power transformers, i.e., CTs and PTs);

earthing arrangements;

reactive compensation;

DC supply arrangement;

auxiliary supply transformer; and

fire-fighting sys ....etc

SUB-STATION EQUIPMENTS & ITS FUNCTIONS
Lightening Arrester
Lightening arrestors are the instrument that are used in the incoming feeders so that to prevent the high voltage entering the main station. This high voltage is very dangerous to the instruments used in the substation. Even the instruments are very costly, so to prevent any damage lightening arrestors are used. The lightening arrestors do not let the lightening to fall on the station. If some lightening occurs the arrestors pull the lightening and ground it to the earth. In any subst ....etc

Power transformer

Transformer is used to step down the voltage from 33 kv voltage to 11kv voltage .
Generally 3.15 MVA, 5 MVA, 10 MVA 33/11kv, / Y transformer are used in 33/11kv s/s.
