To calculate Base Current using the Base Current calculator, you use the formula Base Current (PU) = Base Power / Base Voltage. Base Current (PU) is the ratio of the base power to the base voltage of the system, denoted as Ibase or IpuB. The calculator helps you determine the Base Current based on the provided base power and base voltage.
Base Current is the ratio of base voltage to base power of a system, denoted as I base or IpuB. It is calculated as IpuB = SB/Vbase or Base Current (PU) = Base Power/Base Voltage. Base voltage is the nominal rated voltage of the system, and base power is the product of base current and base voltage.
In the power system, Base Current (PU), denoted as IB, is the rated current, while Base Voltage (PU), denoted as VB, is the nominal rated voltage. The base power, measured in Watt, is the product of base current and base voltage (Sb = IB * VB).
For example, if the base value of voltage had been selected as 13,800 V and the present value is 11,000 V, the value of voltage per unit is VPU = 11,000 ÷ 13,800 = 0.797 PU, or VPU = 0.797 (100) = 79.7% PU Often, nameplate values are taken as base values but this need not be the case.
By observation of the magnitude of the components in the system, a base value of apparent power S is chosen; it should be of the general magnitude of the components, and the choice is arbitrary. In this problem, 25,000 kVA is chosen as the base S, and simulta-neously, at the generator end 13.8 kV is selected as a base voltage Vbase.
A PU value can readily be converted back to a voltage, power, or any other value as long as the base value is known. Although the PU system could most likely be used for systems other than electrical systems, it is probably used mostly with electrical values. The PU system deals primarily with values of power, voltage, current, and impedance.
