Transformer – Special Test
• SFRA test- Sweep Frequency Response Analysis – SFRA is a signature test. First carried out at Factory and then carried out on transformer after receipt at site. This will ensure that transformer safely Transported to site and no fault developed during Transportation. It will detect shifting of Transformer windings from its original position, shorted turns, partial winding collapse, broken or loose clamping structures for windings, core etc.

• Tan Delta & Capacitance Measurement Test for transformer windings and Bushings: It indicates the insulation condition and a key test for diagnosis and maintenance of the Electrical equipment.

• DIRANA TEST: Moisture analysis of paper insulation by dielectric method (PDC+ FDS)

• PD test – Partial discharge measurements of transformers (Online & Offline)

• Transformer Oil test – Routine oil Test- BDV, Moisture in PPM, IFT, Tan delta, DGA, FURAN, Sulfur content etc.
