What is High Voltage?

• Definition:
  • AC voltage > 1000 volts.
  • DC voltage > 1500 volts.
• Applications of high voltage in different media:
  • Gaseous medium.
  • Solid medium.
  • Liquid medium.
• Behavior of these media is essential for:
  • Designing insulation and dielectric materials.
  • Designing protective devices.

Applications of High Voltage Engineering

1. Power System

   • Preference for high voltage AC power transmission.
   • Benefits:
     • Minimizes transmission line losses.
     • Improves overall transmission efficiency.

2. Industries
