Each circuit-breaker bay is factory assembled and includes
the full complement
of isolator switches , grounding switches ( regular or make-
proof ),instrument transformers ,control and protection
equipment, interlocking and monitoring facilities commonly
used for this type of installation .The earthed metal
enclosures of GIS assure not only intensitivity to
contamination but also safty from electric shock.
* Above 66kV using GIS

What is the meaning of floating point earthing in battery backed systems ?
3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
