SFRA (Sweep Frequency Response Analysis) Testing Service
Using OMICRON FRANEO 800 & MEGGER FRAX 101Test Kits
APN ELECTROTECH Engineering Service offers advanced SFRA Testing Services using globally trusted equipment such as OMICRON FRANEO 800 and MEGGER FRAX 101 to accurately assess the mechanical and electrical integrity of power transformers and Reactor
SFRA testing is a proven diagnostic method for detecting winding displacement, deformation, core movement, shorted turns, and transport-related damages without opening the transformer.
What is SFRA Testing?
Sweep Frequency Response Analysis (SFRA) measures the frequency response of transformer windings over a wide frequency range.
Any deviation in the response curve indicates internal mechanical or electrical changes inside the transformer.
SFRA is highly sensitive and is recommended for:
New transformer baseline testing
Post-transport inspection
After fault or short-circuit events
Periodic condition assessment
