Power and distribution transformers

General diagnostic methods include the analysis of oil quality (physical, chemical and

electrical properties, as well as dissolved gases), core and core insulation analysis,

winding and insulation analysis and analysis of the condition of the accessories.

In addition, there are advanced diagnostic methods that address the thermal, electrical

and mechanical condition of a transformer. Thermal assessment techniques are well

established and are typically used to analyze the condition and remaining life of the

transformer insulation. Electrical assessment includes partial discharge (PD) analysis,

which is a powerful tool used to detect incipient faults in the transformer insulation.

Mechanical assessment includes frequency response analysis (FRA), which is applied

to detect changes in transformer winding dimensions due to deformations,

displacements, shorted turns, etc. Other methods are presented in the proceeding

sections.

Our engineers with extensive experience in the transformer field along with modern electrical

and chemical devices have provided a professional team in order to support any customer

in the emergency situation around the world.
