ABB TJCH 5_1VLC000551 Indoor Voltage Transformers,
The TJCH 5 single-pole insulated voltage transformers cast in epoxy resin and designe mostly for insulation voltages of 12 kV to 17,5 kV.
If no other 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 insulated from the earth to a level which corresponds to the rated insulation value.
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,
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 with four secondary windings designate for measurement and/or protection applications having a star connection.
