It is physically impossible to pull any suspended medium tightly enough to get it perfectly straight. The force needed to pull any given length of power line between two poles tight enough to leave no drop by far exceeded the amount of force needed to snap that line in two. The effect of gravity upon that line cannot be overcome.

Power lines may do this on a hot day?
Expand due to the heat, causing them to sag or droop, potentially increasing the risk of contact with trees or other objects.
What happens to a power line when it's a hot day?
On a hot day, power lines can sag due to the expansion of the metal caused by high temperatures. This sagging can lead to power outages or disruptions if the lines come into contact with trees or other obstacles. Additionally, high temperatures can decrease the efficiency of power transmission along the lines.
What are the alternative power sources that can be used instead of a battery?
Alternative power sources that can be used instead of a battery include solar power, wind power, hydroelectric power, and fuel cells.
What holds up power lines?
Power lines are held up by tall metal structures called transmission towers or poles. These structures are designed to support the weight of the power lines and withstand environmental factors like wind and weather. The power lines are typically attached to insulators on the towers to prevent electricity from traveling down the structure.

Why droop ct used in generators?
Droop CT is used to control load sharing of the reactive power b/w paralleled generators.

What does droop mean?
In the context of electrical engineering, "droop" refers to a reduction in voltage or current levels due to an increase in load or demand on a power system. Droop control is a method used in power systems to regulate and maintain stable voltage levels by adjusting the output of generators in response to changes in load. Droop characteristics are defined by the amount of voltage or frequency deviation from the nominal value as a function of the load current.
Why are powerlines more droopy in summer than winter?
Because in Summer, due to warmer weatherm the (power) lines expand on warming. Since the supports do NOT move further apart, then the distance does not alter, so the extra length, due to expansion, allows the lines to 'droop'/sag more.
What is propeller droop?
Propeller droop refers to the decrease in the angle of attack or pitch of a propeller blade when the engine's power output decreases, typically during flight maneuvers or changes in throttle settings. This phenomenon can lead to a reduction in thrust and efficiency, affecting the aircraft's performance. Propeller droop is particularly significant in variable-pitch propellers, where the blade angle can change in response to power demands. Managing droop is essential for maintaining optimal flight characteristics and control.
What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
What is droop setting?
Droop setting is a feature in control systems that allows multiple generators to operate in parallel while sharing a load proportionally. It adjusts the speed and power output of each generator to maintain stability and balance the load. Droop settings help prevent one generator from taking on too much load and ensure a more even distribution of power among multiple generators.
What is the most accurate definition of governor droop?
Governor droop refers to the intentional reduction in the output frequency of a generator as the load increases, allowing for stable operation in power systems. It is a control characteristic where the governor adjusts the fuel or power input to maintain system frequency within acceptable limits, typically expressed as a percentage. This droop ensures that multiple generators can share the load effectively while preventing oscillations and maintaining system stability.

How does the power station deliver electricity to houses?
The power station delivers electricity to houses through a network of power lines and transformers. The electricity is transmitted at high voltages over long distances through transmission lines, which are then stepped down to lower voltages by transformers before being distributed to individual homes through power lines.
