The size and design also have an important effect on the transformer ratings. Transformers can therefore be used primarily for measurement or generation of electric power.

The windings of three-phase transformers can be connected in a variety of circuit configurations. Transformers are regarded as electrical machines even though they contain no moving parts.

Hand-held multimeters are used to measure the characteristics of the transformers.


Students carry out the experiments as specified in the printed manual. If this aspect is not required, then it is possible to dispense with the oscilloscope, isolating amplifier etc.

The complete equipment set allows for experiments on all the most important types of transformer in the W rating class. These practical exercises study exclusively transformers used in energy generation.

Ajouter au panier Fiche technique. The target group is made up of commercial apprentices and students of power engineering.

The experiments are carried out using transformers on training panels in panel frames. Display of current or voltage against time is particularly interesting for three-phase equipment, although it is not essential. Objectives Protective measures and electrical safety Set-up of power generation systems according to circuit diagrams Use of commercial measuring instruments, hand-held multimeters, oscilloscopes, measuring interfaces Transformers are magnetically coupled systems used for transforming AC voltages or matching impedance.

In this case multimeters are sufficient for measuring RMS values. The course offers experiments at an intermediate level for vocational colleges and undergraduate level.
