The size and design also have an important effect on the transformer ratings.

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

Transformers are regarded as autotransformateud machines even though they contain no moving parts. 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 autottransformateur used for transforming AC voltages or matching impedance. In this case multimeters are sufficient for measuring RMS values.

Transformers can therefore be used primarily for measurement or generation of electric power. Hand-held multimeters are used to measure the characteristics of the transformers.

The experiments are carried out using transformers on training panels in panel frames. The course offers experiments at an intermediate level for vocational colleges and undergraduate level.

The windings of three-phase transformers can be connected in a variety of circuit configurations.
