Transformer Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Transformer ratio = Primary phasor/Secondary Phasor
T.R = P/s.p
This formula uses 3 Variables

Variables Used

Transformer ratio - Transformer ratio is the turn ratio (TR) of the transformer.
Primary phasor - Primary phasor is the current in the primary coil.
Secondary Phasor - Secondary Phasor is the current in the secondary coil.

STEP 1: Convert Input(s) to Base Unit

Primary phasor: 9 --> No Conversion Required
Secondary Phasor: 0.45 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T.R = P/s.p --> 9/0.45

Evaluating ... ...

T.R = 20

STEP 3: Convert Result to Output's Unit

20 --> No Conversion Required

What is the use of transformer?

Transformers are most commonly used for increasing low AC voltages at high current (a step-up transformer) or decreasing high AC voltages at low current (a step-down transformer) in electric power applications, and for coupling the stages of signal-processing circuits.

How to Calculate Transformer Ratio?

Transformer Ratio calculator uses Transformer ratio = Primary phasor/Secondary Phasor to calculate the Transformer ratio, The Transformer Ratio formula is defined as the ratio of the primary turns in the primary coil to the ratio of secondary coil turns. Transformer ratio is denoted by T.R symbol.

How to calculate Transformer Ratio using this online calculator? To use this online calculator for Transformer Ratio, enter Primary phasor (P) & Secondary Phasor (s.p) and hit the calculate button. Here is how the Transformer Ratio calculation can be explained with given input values -> 20 = 9/0.45.

FAQ

What is Transformer Ratio?

The Transformer Ratio formula is defined as the ratio of the primary turns in the primary coil to the ratio of secondary coil turns and is represented as T.R = P/s.p or Transformer ratio = Primary phasor/Secondary Phasor. Primary phasor is the current in the primary coil & Secondary Phasor is the current in the secondary coil.

How to calculate Transformer Ratio?

The Transformer Ratio formula is defined as the ratio of the primary turns in the primary coil to the ratio of secondary coil turns is calculated using Transformer ratio = Primary phasor/Secondary Phasor. To calculate Transformer Ratio, you need Primary phasor (P) & Secondary Phasor (s.p). With our tool, you need to enter the respective value for Primary phasor & Secondary Phasor and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
