What to do if TEL TAVRIDA ELECTRIC VCB15 LD Circuit breakers insulation components are contaminated?
If the insulation components of your TEL Circuit breakers are contaminated or defective, the test voltage will not be sustained. Clean or replace the affected components, and then retest.
What to do if TEL TAVRIDA ELECTRIC VCB15 LD modules are not operable?
If the modules of your TEL Circuit breakers are not operable, check the control circuit and change the failed module if necessary.
How to clean TEL Circuit breakers?
To clean TEL Circuit breakers, use a dry napless cloth or a napless cloth soaked in alcohol to clean the insulation, removing any dirt or contamination.
What to do after applying test voltage to TEL TAVRIDA ELECTRIC VCB15 LD Circuit breakers?
If, after applying test voltage to your TEL Circuit breakers, the pole sustains the test voltage for that period, it means the vacuum integrity has been verified. Repeat these actions to check each pole of the ISM.
