High resistance imbalance detected

WebAbnormal heating associated with high resistance or excessive current flow is the main cause of many problems in electrical systems. Infrared thermography allows us to see these invisible thermal signatures of impending damage before the damage occurs. WebFeb 14, 2024 · Higher resistance produces higher losses and more heat per amp for the 120 Hz current than for lower frequency current. The induced currents produce maximum heating at the ends of the rotor body.
