Power frequency dry flashover test diagram

Power frequency dry flashover test diagram is one main part of insulator test and can introduce some problem for electrical insulator including porcelain insulator and composite insulator.

Power frequency dry flashover test diagram

If we would record Power frequency dry flashover test diagram for composite insulator, three composite insulators shall be selected and assembled on the structure of test equipment. The insulators will be connected with suitable power transformer, and the voltage when testing.

The initial applied voltage can be quickly raised to approximately 75% of the dry flashover value, the voltage can be improve less than 5 second. We can record the Power frequency dry flashover test diagram.

Power frequency dry flashover test can be done in accordance with
◆ ANSI C29.1 and ANSI C29.11
◆ IEC 61109

Power frequency dry flashover test diagram
The Power frequency dry flashover voltage value of a test diagram shall be arithmetical mean of not less than five individual flashovers taken consecutively.

Power frequency dry flashover test diagram can be designed in suitable voltage for electrical insulators. Good power frequency dry flashover voltage for electrical insulators which can be used in pollution areas.
