Answer / nishad
Lighting Transformers are used to limit the Fault level in
the Bus of main LT panel by varying the impedance of the
Transformer. If any major fault is occurs, its effect is
affecting only up to the lighting Transformer’s breaker and
it trip itself and prevent the main panel from tripping.
As well as big industries, single phase is not using for
MCC & other equipments. So Neutral is absent in main LT
panel. For lighting purpose we need neutral. So we are
using isolation Transformer for lighting in big industries.
