What else can I help you with?
Distance between ehv lines?
The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
Why is energy lost in power transmission lines?
Increase the voltage in the lines.
Why overhead transmission lines would be more economical than underground transmission lines in high voltage transmission?
Overhead wires do not require insulation, and it is easier to plant poles than dig miles of trenches.
What is distance protection in high voltage transmission lines?

When electricity is transported long distances via large overhead transmission lines the voltage can be transformed up to volts. A. 250000 B. 500000 C. 10000 D. 100000?
When electricity is transported long distances via large overhead transmission lines, the voltage can be transformed up to 500,000 volts (B). This high voltage reduces energy loss during transmission, allowing for efficient delivery of electricity over long distances.
To avoid arcing in transmission lines?
Keep all conductive objects a sufficient distance from the line. Minimum distance depends on the voltage on the line.
Where does electricity go after it goes to the wooden overhead lines?
Overhead distribution lines are made of aluminium not wood.
What is the reason for ferranti effect?
Ferranti Effect causes the receiving end voltage to be more than the sending end voltage. It occurs mainly in long transmission lines when they are lightly loaded. In this condition, the inductance of the lines becomes more resulting in increased receiving end voltage.
What is distance really?
The most common form of protection on high voltage transmission systems is distance relay protection. Power lines have set impedance per kilometre and using this value and comparing voltage and current the distance to a fault can be determined. The ANSI standard device number for a distance relay is 21
What is the required distance to build from a power line?
The required distance to build from a power line varies by jurisdiction and the voltage of the line. Generally, it is recommended to maintain a minimum clearance of 10 to 25 feet from overhead power lines, depending on local regulations and safety standards. For underground power lines, the required distance may be less but still must adhere to specific guidelines set by local authorities or utility companies. Always consult local codes and utility providers for precise requirements.
How many feet away from overhead power lines should mechanical equipment be?
This depends on voltage level, line configuration, line height, loading, sensitivity of equipment, and on and on. The further away the better. Voltage can be induced on equipment near power lines, so I recommend grounding out your equipment as well as possible just in case.
What determines the minimum distance that any part of plant and machinery has to be kept from overhead electricity lines and why?
The minimum distance that any part of plant and machinery must be kept from overhead electricity lines is determined by safety regulations and standards issued by electricity regulatory authorities. This distance is critical to prevent accidents such as electrocutions, fires, and equipment damage due to contact with live electrical lines. Adhering to these regulations helps ensure the safety of workers, prevent power outages, and minimize liability risks for companies.
