3 reasons for increased efficiency loss in rewound motors
Approximately 300,000 motors are rewound in the UK every year, with an average rating of about 12 kW, so the efficiency of rewound motors is extremely important. The loss in efficiency on rewinding depends on the techniques, processes and skill… Read more

Transformer Routine Test – Measurement Of No-Load Loss And Current
The no-load losses are very much related to the operational performance of a transformer. As long as the transformer is operated, these losses occur. For this reason, no load losses are very important for operational economy. No-load losses are also… 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
