Doble M4110

Mechanical forces resulting from system condition such as over current or transportation can cause displacement of the transformer winding. Once a winding becomes distorted, its ability to withstand stress is severely limited and transformer failure is inevitable. The M4110 Leakage Reactance test, also referred to as the short-circuit impedance test, is a reliable indicator of transformer winding deformation. The leakage reactance within a transformer is sensitive to the geometrical changes in the leakage flux path. The leakage flux path is predominantly made up of space between the winding, space within the winding, and space between the winding and the tank wall. The short-circuit impedance of a transformer is calculated by measuring the corresponding current of a voltage applied to the primary winding with the secondary winding short-circuited. With the secondary shorted, the current drawn by the primary is essentially due to the leakage flux.

The M4110 Leakage Reactance Interface enables the M4100 Automatic Insulation Analyzer to measure the short circuit
impedance of transformers, a vital tool for diagnosing winding deformation.
