How we do it
High-voltage testing
01
Preparation
Equipment is disconnected and safety measures are applied.
02
Test
Insulation is tested with elevated voltage for a set time.
03
Contact resistance
Contact resistance of breakers and disconnectors is measured.
04
Report
Results are compared with the norm and reported.
FAQ
FAQ
Why do high-voltage testing?
To find hidden insulation defects before operation and prevent failures.
What equipment do you test?
Circuit breakers and disconnectors, cables, switchgear and transformer insulation.
Why measure contact resistance?
High contact resistance causes contacts to overheat and equipment to fail.
Do you issue a document?
Yes, a report from an accredited laboratory.
