Current per Phase Solution

STEP 0: Pre-Calculation Summary

Formula Used

Current per Phase = (Apparent Power*1000)/(Induced Emf per Phase*3)
I_ph = (S*1000)/(E_ph*3)
This formula uses 3 Variables

Variables Used

Current per Phase - (Measured in Ampere) - Current per Phase in electrical machine design refers to the current flowing through each phase of a three-phase electrical machine, such as an induction motor or a synchronous motor.
Apparent Power - (Measured in Watt) - Apparent power is the combination of reactive power and true power and it is the product of a circuit's voltage and current.
Induced Emf per Phase - (Measured in Volt) - Induced emf per phase is voltage developed across the armature conductor terminals after flux cutting process.

STEP 1: Convert Input(s) to Base Unit

Apparent Power: 48 Kilovolt Ampere --> 48000 Watt (Check conversion here)
Induced Emf per Phase: 800 Kilovolt --> 800000 Volt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_ph = (S*1000)/(E_ph*3) --> (48000*1000)/(800000*3)

Evaluating ... ...

What is meant by 3-phase current?

Three-phase power can be defined as the common method of alternating current power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electric grids worldwide to transfer power.

How do you calculate 3 phase current?

3-Phase Calculations

For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000. Again, assuming unity PF and solving this equation for “I,” you get: I = 1,000kW ÷ 1.732V.

How to Calculate Current per Phase?

Current per Phase calculator uses Current per Phase = (Apparent Power*1000)/(Induced Emf per Phase*3) to calculate the Current per Phase, The Current per phase the formula divides the apparent power by the product of the induced EMF per phase and the number of phases. The multiplication by 1000 is used to convert the apparent power from kilovolt-amperes (kVA) to volt-amperes (VA). Current per Phase is denoted by I_ph symbol.
