Power Transformer Diagnostics
Power Transformer Diagnostics
At Majed Power, we provide comprehensive diagnostic services for power transformers, using both offline and online testing methods to ensure optimal performance, safety, and longevity of your critical electrical assets.
Our approach integrates these diagnostics into Preventive and Corrective Maintenance (PM & CM) programs enabling early fault detection, minimizing risk of failure, and ensuring continued operational reliability.
(A) Offline Tests:
Insulation Resistance Test
Turns Ratio Test
Winding Resistance Test
Dielectric Response Analysis (DFRA)
Sweep Frequency Response Analysis (SFRA)
Partial Discharge Testing (Offline)
Magnetic Balance Test
Impedance and Short-Circuit Test
Temperature Rise Test
Transformer Oil Analysis
(e.g., Dielectric Strength, Moisture Content, Acidity)
