Transformer Station
User Manual
Before the equipment is put into operation for the first time, ensure that the
parameters are set correctly by professional personnel. Incorrect parameter
settings may result in noncompliance with local grid connection requirements and
affect the normal operations of the equipment.
● When operating the transformer, ensure that it is in the no-excitation state,
that is, the high and low voltage sides of the transformer are not powered on.
● Perform insulation tests on the medium-voltage side of the transformer and
the ring main unit before connecting incoming cables and sealing cable holes.
● Before the insulation tests, ensure that no lightning arrester is installed in
cabinet G2 because high voltage may damage the lightning arrester during the
tests.
● During insulation tests on the medium-voltage side and the ring main unit,
ensure that the grounding switch of the ring main unit is turned off, and that
the load switch and disconnector are turned on.
