Dielectric Discharge

This measurement method is usually used to diagnosis multi-layer insulations, which requires the instrument to measure the discharge current and capacitance of the measured object 1 min after the removal of the test voltage. This is a very good insulation diagnosis test to detect deteriorations and other problems in the multiple insulation to be assessed.

• This criteria is a guide and could be slightly changed and be adapted to particular objects under test based on practical experience of the users.
• This method has been established to test high voltage generators installed in electric power plants in some Europe countries.
