What is the 33 11KV substation equipment?

What is the 33 11KV substation equipment?

Power substation consists of: Switchgear: isolators, circuit breakers, earthing switches etc. Controlgear: current transformers, voltage transformers, contactors etc. Protection equipment: relays, fuses, surge arrestors etc.

What is the meaning of 33 11 KV?

33 KV Sub-transmission system is feeding power supply to the HT Consumers and 33/11 KV Substations. 11 KV Primary Distribution system is emanating from 33/11 KV Substations feeding power supply to HT Consumers and 11000/440-220 volts Distribution transformers for supply to LT Three Phase and Single-Phase consumers.

What is 11KV substation?

11 KV Substation. Pole-Mounted Sub-Station: 1. It is a distribution sub-station placed overhead on a pole. The 11 kV line is connected to the transformer (11kV / 400 V) through gang isolator and fuses.

What does 220 kv substation mean?

220kV substation equipment. This is accomplished by suitable apparatus called Substation. For example, generation voltage (11KV or 6.6KV) at the power station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The assembly of apparatus (e.g. transformer etc.)

What is typically inside a substation?

A: A typical substation contains equipment including transformers, circuit breakers, protective relays and associated controls, a control building, steel supporting braces and batteries.

What is HT substation?

HT Panels :HT panels are compact outdoor type systems, which are broadly used in substations. Our product range is prepared from Circuit Breakers or switch fuse on HT side, which protects the equipment from sudden voltage fluctuations.

How much current is in 11kV line?

An 11 kV distribution circuit may carry 150 A in each of its three phases, thus transmitting a power of 3 MW. A 400 V final distribution circuit may carry 200 A in each of its three phases, thus transmitting a power of 150 kW.

What is 400k substation?

400/220/132 KV substation. The substation is fed 1316 MW power from 3 generating stations A,B,C through 400 KV single circuit lines working at around 87% loading. The power is received on 400 KV busbar (double main and transfer bus scheme).

What is the area required for 220 kv substation?

Foundation Mounted type Substation used above 250 kVA and 33 kV….Detailed Solution.

Why are gravels used on a substation floor?

When operating touch an electrical equipment during short curcuit condition,fault current flows through the human body. Stones increase resistance of soil, for this reason, step and touch potential limit decrease when people are working in substations/swicthyard it reduces the possibility of electric shock during work.

Which is better 33 kV or 11 kV substation?

Load up to 150 MVA – voltage rating of 132 kV. Load up to 80 MVA – voltage rating of 66 kV. Load up to 5 MVA – Voltage rating of 33 kV. Thus, when a substation is of rating 66/11 kV, means substation has been designed to receive 80 MVA on 66 kV and it will distribute the received power on 11 kV.

Is there a 33 / 11 kV substation in Savar?

This project paper provides the synopsis assessment of all the systems existing 33/11 kV Dhaka Palli Bidyut Samity-1, Savar. Rural Electrification Board (REB) has the vast electricity distribution network all over the country & the electric power plants are connected with the transmission line to assure the continuity of electric power.

What does 33 kV mean in power rating?

Again, substation of rating 33/11kV means, the substation has been designed to receive 5 MVA of power at 33 kV and it will distribute the same on 11 kV. Thank you!
