Transformer on no load

However, in real world transformers there will always be losses associated with the transformers loading as the transformer is put “on-load”. But what do we mean by: Transformer Loading. If total current supplied from source is Io, it will have one component in phase with supply voltage . When the transformer is operating at no load , the secondary winding is open circuite which means there is no load on the secondary side of the transformer and therefore current in the secondary will be zero.

Practical transformer is different from ideal transformer in many respects.

When an AC sinusoidal supply is connected to.

The current supplied by the source to fulfil the core losses of the transformer.

At no load , secondary current becomes zero du.

If the PF of the load is , find efficiency at full load. The primary winding of the practical transformer has certain resistance and hence small primary copper losses are also present.

Therefore, when the practical transformer is operating, it takes the primary current to supply both core and winding losses. When load is not connected across secondary of transformer , the output power of transformer is zero. As, efficiency is ratio of output power by input power, the efficiency will be zero at no load condition. Actually while performing direct. Also,Iron core has losses due to eddy currents and hysteresis.

In case of no load , the secondary terminal of the transformer is open means the circuit is not complete on the secondary side. This situation clearly indicates that there is no path available for the current to flow in the secondary side. In that case, only few skilled workers will be required to build it. Simple 2d animation describing working of transformer on no load. Reloaded with complete voice description.

A practical transformer is different from an ideal transformer in many respects. An ideal transformer has no losses but practical transformer has Iron losses. Step by step Transformer Phasor Diagram for No Load Condition.
