How to calculate Base Current?

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.

How to calculate AC input current for a DC power supply?

The AC input current for a DC power supply can be calculated using a few known product specifications, as follows: 3-phase AC Input Current Formula: 1-phase AC Input Current Formula: where: Several parameters influence the power supply’s AC input current rating, each of which are described in this section.

What is the difference between 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.

What is the difference between 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).

What is the power factor of a power supply?

A power supply’s power factor is the ratio of true (or real) power, expressed in watts, to apparent (or reactive) power, expressed in vars. Although the current associated with reactive power does not do work at the load, it still must be considered when sizing the AC current draw.

What is the base voltage of a power company?

If the power company delivery voltage is 13.2kV, the base voltage will likely be 13.2kV unless otherwise noted. Voltages are always line-line or phase-phase voltage. Base MVA or Base kVA: A widely used base is 100MVA. But it is possible to select any other base if the operator chooses so. 1MVA=1000kVA.
