Why semicon layer needed in high voltage power cable manufacturing process?
to avoid electrical field strength which may give rise to partial discharge and ageing of power cables
Why transmitting of power at high voltage is economical?
For a given load, the higher the supply voltage, the lower the resulting load current. So, using high-voltages in transmission systems (1) avoid enormous voltage drops along the line, (2) enable cables of realistic cross-sectional area and weight to be used, and (3) minimise line losses. So, high-voltage transmission requires less copper and avoid line losses -resulting in lower costs.
How does the low-voltage circuit controls the power to the high-voltage circuit?
Through a relay or some other kind of high voltage switching device.
How expensive is it to build a high voltage power supply?
There are many guides on the internet for building a high voltage power supply. The average cost for building one of these power supplies is around $20.
For what are high voltage power supplies typically used for?
High voltage power supplies have many uses. It is most commonly used to supply power from a device to the circuit. These are great for people who need to supply their house with power.

Why are there sometimes balls on high voltage electrical wires?
The balls on some power lines are required so that airplane pilots will be able to avoid flying into the lines.

What are the advantages of power transformers over voltage transformers?
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.

Can capacitor increase low voltage to high voltage?
yes a capacitor can improve voltage by improving power factor

How a transformer is so important?
Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.

Does the neon power supply for those beer signs in bars output high voltage AC or DC?
High Voltage AC.
What is on-load tap-changing?
On-load tap-changing is done in electric power supply systems to maintain the supply voltage to customers within limits. Tapping is done by switching extra turns in or out, usually on the high-voltage winding of a transformer. The switching is done by a make-before-break switch to avoid excessive sparking in the transformer, and this enables the switching to be done without interrupting the supply.
What are the names for high voltage power cables?
Electrical conductors
