2. Overcurrent protection

Calculation of protection device adjustment. Modelling and testing of the network in cases of short-circuits of different types.

In the field of the electrical machines:

3. Investigation of induction machines

Measurments of  the no-load and short-circuit parameters and diagrams of the induction motor. Real load motor measurements.

4. Investigation  of the synchronous machines

Measurements of  the no-load and short-circuit parameters and diagrams of the synchronous machine. Line synchronization of the rotating synchronous generator.  Measurement of the V-curves and current diagram

5. Investigation of DC motor

Measurement of output characteristic of a DC generator. Measurement of the mechanical (speed- moment) characteristic of a DC motor with auxiliary excitation. Measurement of efficiency of the whole motor-generator group.

In the field of switchgears and equipments

6. Ideal switch-off of DC and AC faults.

Calculation and measurement of voltage appearing between the contacts of a switch in a model with discret parameters. The effect of the parameteres of the network.

7. Investigation of the electric arc and arc interruption

Measurement of the voltage-current and voltage-length characteristics and comparison to calculation results obtained from arc models. Interruption of AC and DC arc.

8. Investigation of the operation of fuses and miniature circuit breakers.    

Measuring the characteristics of a fuse model and a power circuit breaker.

In the field of insulation and high voltage technology

9. Investigation of dielectric characteristics
