FATSUR has various measurement equipment for conducting electrical tests prior to transformer energization and as part of their predictive maintenance.

Main trials available:

Transformation relation
Insulation Level
Winding Resistance
SFRA
Capacity and tangent delta of windings and terminals
Frequency dielectric response analysis (DIRANA)
Short circuit impedance
Excitement
Dynamic switching resistance
Testing of current transformers (saturation curve, ohmic resistance and transformation ratio)
