Information about Extra High Voltage
Extra high voltage (EHV) refers to an electric potential difference as great as 275,000 volts. A power supply that provides an e.m.f. as great as 275,000 volt is known as an "EHV Power Supply". It is often used in experiments in Physics and Electrical engineering.
It is a commonly used term in TV supplies, television CRTs (cathode ray tube) use this type of supply to deflect electron beams. A CRT supply in a typical TV ranges from 15 kV to 25 kV.
