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.
Display of current or voltage against time is particularly interesting for three-phase equipment, although it is not essential. Students carry out the experiments as specified in the printed manual. The complete equipment set allows for experiments on all the most important types of transformer in autotransformatehr W rating class.
These practical exercises study exclusively transformers used in energy generation.

The target group is made up of commercial apprentices and students of power engineering.

In this case multimeters are sufficient for measuring RMS values. Ajouter au panier Fiche technique. The size and design also have an important effect on the transformer ratings.
Hand-held multimeters are used to measure the characteristics of the transformers. 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.
Transformers are regarded as electrical machines even though they contain autootransformateur moving parts.
The experiments are carried out using transformers on training autotdansformateur in panel frames. The course offers experiments at an intermediate level for vocational colleges and undergraduate level. If this aspect is not required, then it is possible to dispense with the oscilloscope, isolating amplifier etc.
