What is the difference between 33kV and 11kV?

The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.

What is the meaning of 33 11 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. 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.

Is 11KV High Voltage?

Cable Specification: 11KV (Medium Voltage), 22KV (Medium Voltage), 33KV (High Voltage) manufactured to BS7835. Medium Voltage Cable- 11KV and 22KV is suitable for various installations such as providing connections to the grid or, installing wind farms and large generator systems back to the substation.

What is HT and LT transformer?

A low-tension line is a low voltage line and a high-tension line is a high voltage line. In India LT supply is of 400 Volts for three-phase connection and 230 Volts for single-phase connection. High tension or HT supply is applicable for bulk power purchasers who need 11 kilo-Volts or above.

Is most residential wiring 3 phase?

Three-phase power is a three-wire ac power circuit with each phase ac signal 120 electrical degrees apart. Residential homes are usually served by a single-phase power supply, while commercial and industrial facilities usually use a three-phase supply.

What is LT in transformer?

Control Transformers are used as an isolation transformer for voltage regulation. These transformers are designed and manufactured to customer specific requirement.

What is HT power supply?

In vacuum tube technology, HT or high tension describes the main power supply to the circuit, which produces the current between anode and cathode. Other power supplies to vacuum tube circuits include: LT, low tension or A battery, the supply to the filaments or heaters.

What is meant by KVA?

A KVA is simply 1,000 volt amps. A volt is electrical pressure. An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps. On the other hand, a watt (W) is a measurement of real power.

What is difference between HT and LT cable?

Low tension cables have a lower rating where as high tension cables have a higher rating [3.3kV]. Both cables are used in industrial setup and applications, but LT cables are generally used in applications revolving around the 1.1kV range and HT cables are used mainly in power transmission and its distribution.

Which conductor is used in 11kv line?

ACSR Conductors
