What is 33kV transmission line?
33kV to 11kV transformers steps down the the voltage to a safe level, which is then distributed via 11kV feeders to homes and businesses. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.
How do I know my 33kV line?
For the 11KV transmission line, generally Double Pole(DP) structure is used. In a transmission line, if three pieces of disc insulators per phase are connected, then the KV of the transmission line is 33KV.
What is the safe distance from 33kV line?
Min. Safe Vertical Distance above Railway Track
| Description of Clearance | Distance (Min) |
|---|---|
| Stay wires | 5.5 Meter |
| Conductors up to 33 kV | 6.5 Meter |
| Conductors above 33 kV to 220 kV | 7.5 Meter |
| Conductors above 220 kV. | 8 Meter |
Which conductor is used in 33 kV line?
Purity: 100% Surface Treatment: Galvanized. Power/Voltage: 11KV,33KV. Conductor: Copper.
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.
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 the meaning of 33 11 KV?
What is the current in 11kV line?
Take a 11kV/415v, 500KVA distribution system. Then maximum current on HV side = 500/{sqrt(3) * 11} = 26.24 A. maximum current on LV side = 500/{sqrt(3) * 0.415} = 695.6 A. Similarly you can compute for your data.
What distance is safe for 11 kv power lines?
As per the Indian Electricity Act, buildings should maintain a horizontal distance of 1.2 metres from 11kV lines and 4 metres from 66kV lines.
How far should a home be from power lines?
This is the most important rule: Work at a safe distance from all power lines. The Occupational Safety and Health Administration (OSHA) requires that equipment be kept at least 10 feet away from power lines with voltages up to 50kV.
Which one is mostly used conductor?
Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Aluminum and most other metals do not conduct electricity quite as good as copper.

What kind of structure is a transmission tower?
A transmission tower or power tower (electricity pylon or electric pylon in the United Kingdom, Canada and parts of Europe) is a tall structure, usually a steel lattice tower, used to support an overhead power line. They are used in high-voltage AC and DC systems, and come in a wide variety of shapes and sizes.
