Four most important power transformer analyses
To be clear, nowadays, you can perform dozens of analyses on a transformer, and all of them are very important. However, it should not be that hard to separate a few of them, the most important ones. Let’s discuss insulation,…...

How Bad Harmonics Influence The Work Of Rotating Machines (Induction Motors)
The presence of harmonics in the work of induction motors can be pretty bad. Why? They produce elastic deformation, that is, shaft deflection, parasitic torques, vibration noise, additional heating, and lower the efficiency of rotating machines. The movement of the…...

How To Reduce Transformer Losses At Design Stage
Design changes to reduce transformer losses, just as in a motor, always involve trade offs. For example, consider varying the cross-sectional area of the transformer core. An increase tends to lower no-load loss while raising the winding loss. An increase… Read more

Five factors that mess up motor efficiency and how to improve it
It must be emphasised that the standard electric motor is already a very efficient device with efficiencies above 80% over most of the working range, rising to over 90% at full load. However, because of the high energy consumption, and the… Read more

Transformer Heat, Copper and Iron Losses
The thermal ratings of a transformer are determined by the following three factors: The amount of heat produced in the windings and connections. The amount of heat produced in the iron core. How effectively the heat can be removed from… Read more
