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.

These practical exercises study exclusively transformers used in energy generation.

The course offers experiments at an intermediate level for vocational colleges and undergraduate level. In this case multimeters autotransformatur sufficient for measuring RMS values. 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. The target group is made up of commercial apprentices and students of power engineering.

If this aspect is not required, then it is possible to dispense with the oscilloscope, isolating amplifier etc. Topics Voltage equation and equivalent circuit Measurement without load, with load auottransformateur with a short circuit Determination of self-inductance, magnetic coupling and leakage Losses, changes in voltage and efficiency 1 – – Requis 2 – – Requis 1 – – Alternative 1 – – Alternative 2 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Alternative 3 – – Requis 1 – DG autotransformateyr Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Alternative 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – – Requis 1 – EN – Requis.

Autotranformateur complete equipment set allows for experiments on all the most important types of transformer in the W rating class. Hand-held multimeters are used to measure the characteristics of the transformers. Display of current or voltage against time is particularly interesting for three-phase equipment, although it is not essential.

Ajouter au panier Fiche technique. The experiments are carried out using transformers on training panels in panel frames.

The size and design also have an important effect on the transformer ratings. Students carry out the experiments as specified in the printed manual.

Transformers can therefore be used primarily for measurement or generation of electric power.
