Sweep frequency response analysis is a crucial procedure for evaluating the mechanical and electrical integrity of power transformers. Sweep frequency response analyzers, available for rent from ATEC, are indispensable tools in this process, aiding in the detection of potential issues or damage within the transformer. These issues may include winding deformation, displacements between high and low voltage windings, partial winding collapse, shorted or open turns, faulty grounding of core or screens, core movement, broken clamping structures, and problematic internal connections.
ATEC's sweep frequency response analyzer rentals allow for the precise measurement of the transformer's current capacitance. These measurements are then compared to the initial test conducted during installation. Any deviations in capacitance or inductance indicate changes in the condition of the insulation, winding, or other components, signaling potential issues that require immediate attention
