How we do it
Transformer and substation testing
01
Insulation
Insulation resistance of windings and equipment is measured.
02
Windings
Winding resistance and turns ratio are determined.
03
High voltage
Dielectric strength of insulation is tested with high voltage.
04
Report
Results are issued as a test report and inspection report.
FAQ
FAQ
Which transformer parameters do you check?
Insulation resistance, winding resistance, turns ratio and dielectric strength of insulation.
Do you check the whole substation?
Yes: insulation, earthing and protection of substations and switchgear.
How is inspection different from testing?
Testing is a laboratory measurement; inspection assesses conformity with requirements. We are accredited for both.
Do you issue a document?
Yes, a test report or inspection report.
