Magnetic Core Balance Test of Power Transformer: Procedure, Results & Interpretation
The magnetic core balance test is performed in a three phase transformer to check the symmetry of the magnetic path in the core and detect interturn faults in the power transformer. This test is basically based on the principle of flux linkage and it is expected that since …

Sweep Frequency Response Analysis (SFRA) Test of Transformer: Complete Guide
Sweep Frequency Response Analysis or SFRA is a test which is used to assess the mechanical integrity of the transformer’s main part which is core, winding and clamping structure by injecting low voltage signals from few Hz to several MHz and measuring the response of transformer at various …
