operation or in individual cases, voltage
transformers may also be supplied loose.
These voltage transformers must be dismantled
prior to installation of the cables and re-installed
after high voltage testing of the switchgear
system.
Voltage transformers for integrated busbar
measurement (transformers of metering 2 and 3
in fig. 3.3.7.1) are supplied loose and have to be
installed at site after high voltage testing.
Important note
The weight of a voltage transformer can
