Across
  1. 4. For voltages beyond 66 kV, equipment is invariably (constant) installed outdoor, the substation is called as
  2. 5. The substation either converting AC to DC or vice versa
  3. 6. The substations are located at the load centers, where the sub transmission/primary distribution voltage is stepped down to secondary distribution voltage (415/240 V)
  4. 8. The substation involving voltages between above 400 kV
  5. 9. In thickly populated areas, the space available for equipment and building is limited and the cost of land is high, the substation is called as
  6. 10. For voltages up to 11 kV, the equipment of the substation is installed indoor because of economic consideration, the substation is called as
  7. 12. The generated voltage, which is usually low (3.3, 6.6, 11 or 33 kV), is stepped up to primary transmission voltage so that huge blocks of power can be transmitted over long distances to the load centres economically.
  8. 13. The substations which supply power to individual industrial concerns
  9. 14. For transformers of capacity above 250 kVA the transformers are too heavy for pole mounting, the substation is called as
Down
  1. 1. The substations from where bulk power is transmitted from one point to another point in the grid
  2. 2. The substation simply perform the switching operations of the power lines
  3. 3. The substation which changes the supply frequency
  4. 7. The substation involving voltages between 132 kV and 400 kV
  5. 11. Assembly of apparatus which transfers characteristics of electrical energy from one to another
