3 High Voltage BushingsPlus possible grounding bushings and/or test bushingsMain physical principleWhat makes the transformer possible are two physical facts:1) A current flowing through a conductor will create on its surroundings a magnetic field.2) A varying magnetic field will cause a voltage to...
1. High voltage bushings are of two types and are made of wet process porcelain: • Speed wrench operable eyebolt bushing for cover mounting. • Spin-top bushings for either cover or side-wall mount. 2. Tap changers compensate for small voltage variations ...
