    8. Synopsis
    I. Design practice and software tools in Power System Transmission and
    1.    Load profile and voltage distribution analysis in a low voltage
    grid. Fault current calculation and selection criteria for fuse rating.
    2.    Analysing the load and control characteristic of a high/medium
    voltage (120/20 kV) transformer substation. Controlling the power factor and
    voltage quality by means of shunt capacitors.
    3.  Deriving zero sequence models of Y/y , D/y, D/z and Y/d transformers
    for non-symmetrical fault and serial failure analysis. 
    4.   Fault current distribution on a 120 kV HV transmission line, analyzing
    the influence of grounding conditions and calculation of potential rise of
    faulted tower and earthing grid of nearby substations.
    II. High voltage measurements

    5. Ideal switch off in case of DC and AC faults. Application of concentrated parameter model to calculate transient recovery voltage (TRV) between the connectors of a switchgear. Effects of the network parameters on the TRV.

    6. Examination of steady state arc and extinguishing DC arc. Measurement of voltage vs. current and voltage vs. arc length characteristics. Comparing meaurement results to the ones calculated from arc models. Examination of how network parameters and arc extinction devices influence the switch off process.

    7. Examination of AC arcs, its properties and extinction. Examination of arc hysteresis and time functions of arcs in AC circuits at different phase shift. Examination of influence of switch on angle, phase shift and arc extinction devices on the switch off process.

    8. Examination of fuses and miniature circuit breakers (MCB). Measurement of the switch off time vs. current characteristics of fuse models and an MCB.

    III. Electrical machines

    9. Power engineering measuring technique

    10. 3 phase transformer

    11. Induction machine

    12. DC machine

    13. Synchronous machines


    9. Method of instruction

    Laboratory measurement are 3 hours long 12 times in the semester, with one opportunity for supplement measurement.

    11. Recaps

    Maximum two opportunities are provided in one semester for supplement failed measurements (typically the last week before the end of semester).

    12. Consultations

    Consultation time is available on-demand after preliminary agreement.

    13. References, textbooks and resources Laboratory measurement programs are based on measurement guides in electronic form, supplied on the department’s homepage.
