ABB TJC 7.1 1VLC000535 Indoor Voltage Transformers

ABB TJC 7.1 1VLC000535 Indoor Voltage Transformers,
The TJC 7.1 single-pole insulated voltage transformers casted in epoxy resin,
and designe mostly for insulation voltages of 36 kV.
Insulation voltages different from the above are the subject of an agreement between the manufacturer and the customer.
If no a different value is require, the transformers are manufacture,
with a overvoltage factor of 1.9 x Un/8 hrs. One outlet of the primary winding,
including the respective terminal is insulate from the earth to a level,
which corresponds to the rate insulation value.
The other outlet of primary winding with terminal is earthe during the operation.
furthermore The transformer is designe to support up to four secondary windings,
although standard configurations typically include two or three secondary windings.
One, two or three of these secondary windings are designate for measurement,
and/or protection applications in star connection,
olso while the other last one is intende for integration into an open-delta configuration,
within a three-phase system. Upon request can be manufacture VTs,
furthermore  with four secondary windings designate for measurement and/or protection applications having a star connection.
