What type of device is used to convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor?
To convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor you use a transformer.
What tool is used to check voltage?
by using a multimeter we can find line voltage.
Does line to ground voltage always half the value of line to line voltage?
Line to Ground voltage = line to line voltage / 1.73AnswerIt depends what configuration is being measured. In the case of the secondary of a split-phase distribution transformer used to supply residences in North America, the answer is yes. In the case of a star (wye) connected secondary distribution transformer used to supply residences in Europe, no: the line to ground voltage will be as described in the first answer.
Why tap changer is required?
Tap changers are used to change transformer winding ratios by a specified amount (+/- 10%, for example). This allows more voltage control of one side with respect to the other. For a distribution transformer, as load increases, the voltage will sag. If it sags too far, a tap changer will be required to raise the voltage to acceptable values.
What is the voltage used for megger check of aircraft looms?
I did them with a 1,000 volt megger .

Binary datda is put on a line of a bus by placing voltage on that line?
Data bus is used to transit data from one place to another by placing voltage. This indicates that data is traveling but voltage is used to hold the line and is not travelling.

As a battery ages and is used up what will the internal resistance be?
As it ages, its Kirchhoff virtual 'internal resistance' increases. Pictured this way, the practical effect is that the open-circuit voltage of a failing cell still measures good, but the voltage quickly sags when you try to draw any current from it

Why telephone line has negative voltage?
A negative live voltage is used to prevent electroytic corrosion on the copper wires.
Can 24volts be line voltage?
No. Line voltage is 120v or some multiple there of. It is the potential that comes in from the grid and is found on the hot conductor in your house wiring. 24 volts is "low voltage" and tends to be used only for switching and lighting. Also, 24 volts is often DC (though not always) while line voltage is invariably AC
What are the used of multimeter?
to check voltage, current , polarity of of material,etc
What is the difference between line voltage and low voltage?
Answer for USA, Canada and countries running a 60 Hertz supply service.Line voltage is a term that is used to describe the voltage that is used to operate a specific device. A service that comes into a building would be considered line voltage. For a Class 1 circuit the top voltage for low voltage installations is 30 volts at 1000 vA. For a Class 2 circuit the top voltage for low voltage installations is not under 30 volts and not over 60 volts at 100 vA. Voltages used above 750 volts are considered high voltage installations.
Function of tap chenger in transformer?
The tap changer changes the ratio of primary to secondary windings by physically adding or subtracting windings from the primary or secondary. An on load tap changer (LTC) allows dynamic voltage control, which is important when loading of transformers, and the system in general, varies (if the primary voltage sags, the LTC can be used to increase the secondary voltage so customers don't see this sag).
What voltage should be used when making three phase calculations?
With a three-phase system the voltage quoted is the line-to-line voltage between any two live lines. To find the line-to-neutral voltage divide by 1.732 which is sqrt(3). The power supplied from each phase is the current times the line-to-neutral voltage (times the power factor if less than 1). To find the total power when the currents are equal, multiply by 3.
