ABB TPU 5x.xx Indoor Supporting Current Transformers

ABB TPU 5x.xx Indoor Supporting Current Transformers,
The TPU 5x.xx transformers cast in epoxy,
resin and designed for insulation voltages up to,
17.5 kV. The 13.8 kV and 7.2 kV versions have the,
same dimensions as the 17.5 kV. For certain types,
of panels there is a need for extra long creepage,
distance on the transformers. For this purpose,
you can order current transformers with „ribs on,
the top”. The transformers are manufacture in,
conformity with dimensions stated hereunder.
The TPU 5x.xx transformers are designe as single-turn or multi-turn versions,
with one transformer ratio or with double ratio having the possibility to be reconnectable on the primary or on,
the secondary side. The number of secondary,
windings (from 1 to 6 – max. 12 secondary terminals – 2 rows), depends on the combination of the,
technical parameters (such as the accuracy class,
burden, short-circuit current, overcurrent factor…) and the transformer dimensions size.
