Primary Current using Primary Parameters Solution

STEP 0: Pre-Calculation Summary

Formula Used

Primary Current = (Primary Voltage-EMF Induced in Primary)/Impedance of Primary
I₁ = (V₁-E₁)/Z₁
This formula uses 4 Variables

Variables Used

Primary Current - (Measured in Ampere) - Primary Current is the current which is flow in the primary winding of the transformer. The primary current of the transformer is dictated by the load current.
Primary Voltage - (Measured in Volt) - Primary Voltage means the level of voltage at facilities at which electric power is taken or delivered, generally at a level between 12 kV and 33 kV, but always between 2 kV and 50 kV.
EMF Induced in Primary - (Measured in Volt) - EMF Induced in Primary Winding is the production of voltage in a coil because of the change in magnetic flux through a coil.
Impedance of Primary - (Measured in Ohm) - The Impedance of Primary Winding is the impedance you anticipate the device connected to the transformer primary side to have.

STEP 1: Convert Input(s) to Base Unit

Primary Voltage: 240 Volt --> 240 Volt No Conversion Required
EMF Induced in Primary: 13.2 Volt --> 13.2 Volt No Conversion Required
Impedance of Primary: 18 Ohm --> 18 Ohm No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I₁ = (V₁-E₁)/Z₁ --> (240-13.2)/18

Evaluating ... ...

I₁ = 12.6

STEP 3: Convert Result to Output's Unit

12.6 Ampere --> No Conversion Required

FINAL ANSWER

12.6 Ampere <-- Primary Current

What type of windings are used in a transformer?

In core type, we wrap the primary, and secondary windings on the outside limbs, and in shell type, we place the primary and secondary windings on the inner limbs. We use concentric type windings in core type transformer. We place a low voltage winding near the core. However, to reduce leakage reactance, windings can be interlaced.

How to Calculate Primary Current using Primary Parameters?
