  • Wideband Transformers
    Wideband transformers couple signals magnetically from input to output terminals with optimum transmission fidelity over broad frequency ranges. Major objectives in their use are: 1. Impedance matching for maximum power transfer. 2. Coupling between unbalanced and balanced circuits. 3. DC isolation

  • Infrared Inspections of Dry-type Transformers
    . Transformers with balanced loads will exhibit similar temperatures between windings. 3) Compare each phase coil to itself. Properly operating coils should exhibit no pronounced hot or cold spots. 4) Inspect voltage tap jumper connections. Both connections should be the same temperature. In most cases
