Why do power lines carry electricity at 440000 volts when it is generated at 3000 volts?

For any given load, P, the higher the supply voltage, V, the lower the resulting load current, I (i.e. I=P/V). By reducing the load current, conductors with a lower cross-sectional area can be used and save on their weight and the cost of copper or aluminium. A secondary advantage is that a lower load current also results in lower line losses (i.e. P = I2R).

Are overhead power lines insulated?

Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.

What is house load of power plant run parallel with grid and how to calculate it?

House Load of a Power Plant is also known as Auxiliary Power Consumption or Units Used on Works.

It is the electrical power needed to drive the pumps and fans that support the operation of the power plant.

Typically the power plant metering is set up to measure the electricity produced by the generator at the terminals. A seperate meter will measure the electricity used by the auxiliaries, at the unit transformer.

Auxiliary Power Consumption is often expressed as a percentage of Units Generated, so:

Aux Power = ( Units Used on Works / Units Generated ) x 100 %

% MWh MWh

Typical Auxiliary Power Consumption depends on the type of plant:

Plant Type

%

Coal-fired Thermal

6.5 - 8.0

Open Cycle Gas Turbine

2.5 - 3.5

Combined Cycle Gas Turbine

1.0 - 1.5

What are the operating costs of a swimming pool in Southern California?

These can vary greatly depending on your location, pool, pump, filter, heater sizes and ratings. Do you have a concept as to how much use it will get? The cost of gas, electricity, chemical costs -- do you want pool service -- do it yourself -- Knowing some of the above will give you a start as to how long you need to run the equipment, how much chemicals to use and if you have automatic or semiautomatic devices. In other words there are too many variables to give you an accurate answer without knowing the details of your pool. Best ballpark answer is to give you a direction and that would be to ask your neighbors who have pools.
