Across
  1. 3. The emergence of Gas Insulated Switchgear (GIS) and GIS was advantageous in terms of space-saving and reliability, especially for high-voltagr application.
  2. 5. To isolate a circuit but are designed for infrequent operation.
  3. 6. They are devices that physically move to start or stop current flow in a circuit.
  4. 10. They are designed to protect circuits from damage by excess current.
  5. 15. Capable of breaking current while under load, making them suitable for switching circuits.
  6. 16. They are made to ensure that a circuit is fully off before maintenance or servicing can be done.
  7. 18. It is cheap and available, also it is non-toxic and eco-friendly.
  8. 19. Protect electrical systems from lightning damage.
  9. 20. Backbone of switchgear.
  10. 22. The Early forms of switchgear were simple knife switches.
  11. 23. They protect circuits from overcurrent.
  12. 24. It is vital and also acts as a safeguard.
Down
  1. 1. The advent of digital and microprocessor-based control system revolutionized switchgear.
  2. 2. They used oil to stops arcs. They were more reliable than older air-insulated switches.
  3. 4. It is an electrical device that is widely used for switching circuits on and off.
  4. 6. It has high dielectric strength. This allows compact designs. It is resistant to deterioration and performs consistently over a wide temperature range.
  5. 7. Designed to lessen the effects of electrical arcs.
  6. 8. Higher dielectric strength than air, non-flammable, chemically stable.
  7. 9. They protect the internal parts from things like dust, moisture, and impacts.
  8. 11. These transformers convert high-voltage and high-current signals.
  9. 12. These switches provide complete isolation of a circuit, ensuring that no current can flow through it during maintenance or repairs.
  10. 13. A switch that connects or disconnects two circuits.
  11. 14. Better insulating properties than, air cooling benefits, oil has high dielectric strength.
  12. 17. House the control circuitry and instruments.
  13. 21. The introduction of vacuum and SF6 (sulfur hexafluoride) as arc extinguishing media marked significant advancement.
