Induction machines are sometimes called the workhorses of industry. They are cheap and robust and applied in a wide variety of applications. In this experiment the students will get familiar with the induction machines and their character.

The stuy goals are;

• Be able to determine the parameters of the equivalent circuit of an induction machine.
• Be able to measure a part of the torque-speed characteristic of an induction machine.

The following characteristics of an induction machine will be examined during the experiments:

• Resistance measurement of the induction machines
• No-load test of the induction machine
• Blocked-rotor test of the induction machine
• Torque-speed characteristic of the induction machine

Synchronous machines are mostly used as generators. They can be used in island operation, for example on board of a ship or an aircraft, or connected to the grid, for example in a power station or a combined heat and power unit. In this experiment, both will be tested and the students will get familair with characteristics of Sychronous machines.

The study goals are;

• Be able to synchronize a synchronous machine with the grid.
• Be able to realize different operating points of a synchronous generator with different loads.

The following characteristics of an Synchronous machines will be examined during the experiments;

• Connection of the synchronous machines.
• Connection of the asychronous machines.
• Island operation of a synchronous machine.
• Grid connection of a synchronous machines.
