Electrical tests
Diagnostic electrical testing for transformers and substations
Each test isolates a different failure mode. We run them with Omicron and Megger instrumentation, correct for temperature and deliver a protocol compared against standards and asset history.
Turns ratio test (TTR)
Detects shorted turns, open windings and tap-changer faults by comparing the measured ratio against nameplate.
Ver másPower factor & Tan Delta
The most sensitive indicator of moisture, contamination and ageing of the paper-oil insulation.
Ver másInsulation resistance & polarization index
Fast screening for moisture and contamination of the insulation system.
Ver másDissolved gas analysis (DGA)
Detects arcing, partial discharge and overheating from the gases dissolved in the oil — without de-energizing.
Ver másFrequency response analysis (SFRA)
The only test that detects mechanical deformation of windings and core after a short circuit or transport.
