Transcript
• High voltage equipments must be tested in a high voltage laboratory according to standards.
• Disruptive, breakdown, withstand voltage and partial discharge can be performed in the lab.
• High voltage testing is used to access the insulation property of gas, liquid and solid.
• High voltage test should be performed according to the standards (IEC, ANSI, IEEE, BSI etc.)
