ABB TPU 6x.xx Indoor Supporting Current Transformers,
The TPU 6x.xx transformers cast in epoxy,
resin and designed for insulation voltages up to,
also 25 kV. The 24 kV version has the same dimensions,
furthermore as the 25 kV. For certain types of panels there is,
also a need for extra long creepage distance on the,
furthermore 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 6x.xx,
also 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,
furthermore to 6 – max. 12 secondary terminals – 2 rows), depends on the combination of the technical parameters (such as the accuracy class, burden,
moreover short-circuit current, overcurrent factor…) and,
moreover the transformer dimensions size.
Technical data
The transformer can be mounte in any position.
The transformer body is fixe by using four
screws. Earth clamp M8 is on the transformer
base plate.
