Power System5

  1. EHV transmission has which of the following advantages ?

    EHV means extra high voltage transmission.

  2. Absence of skin effect, lower line cost, less corona effect are the features of which of the transmission system ?

    HVDC system is high voltage DC transmission.

  3. Which equipment do not supply reactive power in HVDC converter stations?

    Static shunt capacitors serve the purpose instead of series capacitors.

  4. Inside the station of the broad gauge line what is the clearance between track and lowest conductor for operating voltages from 650 V – 33 kV ?

    8.6 m is the clearance between track and lowest conductor for operating voltages from 650 V – 33 kV inside the station of the meter gauge line.

  5. The loads on 3 -Φ, 4 - wire distributors are usually

    Under construction.

  6. Backup protection, frame leakage protection and differential over current protection are the protection schemes for which element?

    Under construction.

  7. GIS substation is referred as

    Under construction.

  8. There are how many types of tariffs?

    Under construction.

  9. The daily load of an industrial consumer is as follows: 100 kW for 9 hours, 125 kW for 6 hours, 50 kW for 7 hours and 5 kW for 2 hours. Determine energy consumption per year?

    Daily energy consumption = 100 × 9 + 125 × 6 + 50 × 70 + 5 × 2 = 2010 kWh Annual consumption = 2010 × 365 = 733650 kWh.

  10. There are how many types of power consumers?

    Types- domestic, commercial, agriculture, industrial, bulk, street lighting and water supply.

  11. The area under load curve represents

    Under construction.

  12. The knowledge of diversity factor helps in computing

    Under construction.
