Efficiency of Transformer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Efficiency = Output Power/Input Power
η = P_out/P_in
This formula uses 3 Variables

Variables Used

Efficiency - Efficiency can be defined as the ability to achieve an end goal with little to no waste, effort, or energy.
Output Power - (Measured in Watt) - Output power is the power delivered to the load after losses.
Input Power - (Measured in Watt) - Input power. Means the product of the direct voltage applied to the last radio stage and the total direct current flowing to the last radio stage, measured without modulation.

STEP 1: Convert Input(s) to Base Unit

Output Power: 120 Kilowatt --> 120000 Watt (Check conversion here)
Input Power: 135 Kilowatt --> 135000 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η = P_out/P_in --> 120000/135000

Evaluating ... ...

η = 0.888888888888889

STEP 3: Convert Result to Output's Unit

0.888888888888889 --> No Conversion Required

FINAL ANSWER

0.888888888888889 ≈ 0.888889 <-- Efficiency

Equivalent Reactance of Transformer from Secondary Side

LaTeX Go Equivalent Reactance from Secondary = Secondary Leakage Reactance+Reactance of Primary in Secondary

Equivalent Reactance of Transformer from Primary Side

LaTeX Go Equivalent Reactance from Primary = Primary Leakage Reactance+Reactance of Secondary in Primary

Primary Leakage Reactance

LaTeX Go Primary Leakage Reactance = Reactance of Primary in Secondary/(Transformation Ratio^2)

Reactance of Primary Winding in Secondary

LaTeX Go Reactance of Primary in Secondary = Primary Leakage Reactance*Transformation Ratio^2

Efficiency of Transformer Formula

LaTeX Go

Efficiency = Output Power/Input Power
η = P_out/P_in

What material is used for the cores of a transformer and why ?

Lamination of specially alloyed silicon steel (silicon content 4 to 5%) are used due to its high electrical resistance ,high permeability non-ageing characteristics and minimum iron loss .

FAQ

What is Efficiency of Transformer?

Efficiency of Transformer is the ratio of output power to the input power of transformer.It describes how much power is lost while voltage conversion and is represented as η = P_out/P_in or Efficiency = Output Power/Input Power. Output power is the power delivered to the load after losses & Input power. Means the product of the direct voltage applied to the last radio stage and the total direct current flowing to the last radio stage, measured without modulation.

How to calculate Efficiency of Transformer?

Efficiency of Transformer is the ratio of output power to the input power of transformer.It describes how much power is lost while voltage conversion is calculated using Efficiency = Output Power/Input Power. To calculate Efficiency of Transformer, you need Output Power (P_out) & Input Power (P_in). With our tool, you need to enter the respective value for Output Power & Input Power and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
