Three phase
isolation transformer is mainly used in low voltage distribution
system, isolating load from power supply. Distribution system is
divided into TN, TT and IT. The first T indicates that the neutral
point of power transformer is directly grounded. I indicates the
neutral point of power transformer is non-grounded(or grounded
through high impedance). The second T indicates that the case of
electrical equipment is directly grounded, but have no connection
with the power grid of ground system. And N indicates that the case
of electrical equipment is connected with the grounded neutral wire
of system.
TN system: the
neutral point of power transformer is grounded and the case of
equipment is partially connected with neutral
wire.
TT system: the
neutral point of power transformer is grounded and the case of
equipment adopts protection grounding.
IT system: the
neutral point of power transformer is non-grounded but the case of
equipment adopts protection grounding.
In the IT system,
isolation transformer can prevent electric shock, protect the
connected equipment from insulation damage and make the neutral
point isolated.
