Transformer Construction

It is advised that staggering of the butt joints

Stepping of the core is implemented in the core to

Consider two transformers X and Y having exact ratings, but have flux densities of 1.5T and 2T respectively. The weight of the transformer A per KVA will be

The primary and secondary of a transformer are ________ coupled but _______ connected.

The most widely used material in the core of the transformer is

Core type transformers have, LV and HV windings are arranged such that

Transformers do not require any type of cooling as it well ventilated.

We can employ transformers for a power range of

A transformer has comparitively much higher efficiency than a similar induction machine due to

Consider two transformers X and Y having identical ratings, but have flux densities of 1.5T and 2T respectively. The weight of the transformer B per KVA will be

A coupling magnetic field inside a rotating machine or static machine like transformers must involve with
I. electrical system to extract energy from electrical system.
II. mechanical system to extract energy from electrical system.

It was needed that to isolate dc noise coming from the transmitted signal, to attain the same which machine can be used without suffering significant loss

The shell type transformers have, LV and HV windings are arranged such that

A coupling magnetic field inside a rotating machine or static machine like transformers must involve with

The leakage flux is the flux in side the transformer which

I. Pulse transformers use soft ferrites.
II. The transformers used in the radio recievers use air core.
