When doing per unit analysis, voltage and power are normally the independent values, while impedance and current are normally dependent. Check and see what voltage your generator is producing, and follow it through any Transformers, converting it accordingly and write it down in each zone. Any time the voltage changes level, you have to recalculate what your per unit current and impedance are. Choose some X amount of power to be constant throughout the entire system.
Z = impedance; V = voltage; S = complex power; I = current.
(Z base) = (V base)^2 / (S base)
(I base) = (V base) / (S base)

What is voltage unit?
Voltage is "electrical pressure", so to speak, or energy per charge. Volts is joules per coulomb.
What is regulation of a transmission line?
Regulation has to do with keeping the voltage at a desired value. This is often put in a per unit value, which you can think of as a percent of nominal. So if the desired voltage is 34.5kV, and the actual voltage is 33.8kV, the voltage is .98 per unit. There are regional and national rules on how low or high voltage can be. If the voltage strayes from this, it must be regulated back to an acceptable value.
What is the base unit of voltage?
The base unit of voltage is the volt, a combined unit meaning joules per coulomb.AnswerThe SI unit for voltage is the volt (symbol: V), which is a derived unit -not a base unit. There are seven base units in the SI system: metre, kilogram, second, ampere, candela, kelvin, and mole. SI units which are not base units are termed 'derived units'.
What is the basic unit of voltage called?
the basic unit of voltage is watts
Is current measured in volts?
The Ampere is the unit of electric current. It depends upon a voltage in order for it to occur, and the Volt is that unit. The Ohm is the unit of resistance and represents the difficulty of moving the electrons by the voltage.
What is the name of the unit for Energy per Unit of Charge?
= voltage
What is voltage unit?
Voltage is "electrical pressure", so to speak, or energy per charge. Volts is joules per coulomb.
What is a potential difference and what SI unit is used to measure it?
it is a quantity defined as work done per unit charge.it has same unit as voltage which is volt represented by 'V'.

What is the difference in energy per unit of charge between two points in a circuit?
voltage

Voltage is measured in what unit?
This unit is called volts.
What is the unit for potentional difference?
Voltage (V) is the unit of p.d,The voltage itself s the difference in electric potentiel between two different points.It Just means the work done per unit charge can also be expressed as J C-1
What is the difference in potential between two charges called?
Voltage.The correct term for the amount of energy per unit of charge is potential difference.Energy = Charge * VoltageSimple rearranging gives: Voltage = Energy / ChargeTherefore a volt can be defined as a "joule per coulomb".
What is the unit voltage is measured in?
ummm... ...voltage?
The difference in energy per unit charge as a charge moves between two points in the path of a circuit?
voltage
What does 10 volts mean?
Volt is the unit of voltage. It refers to the difference in energy per unit charge, when you move electrical charges between two points.Another good way to think about voltage is to think about Ohm's Law: V=IR. Through a given resistance, a higher voltage will produce a larger electrical current (more electrons per second).
