Bushing (electrical) - Function
... All electrically conducting materials generate an electric field when energised with a voltage ... When an energized conductor passes near any part of material that is at earth potential, its electric field can be affected and distorted by the shape of the earthed material ... Voltage from the conducting material can be attracted towards the earthed material, and if the electric field becomes of sufficient strength, this can lead to the formation of a leakage path ...

Famous quotes containing the word material:

    Desperation is the raw material of drastic change. Only those who can leave behind everything they have ever believed in can hope to escape.
