Description
The TPO 7x.xx transformers are cast in epoxy resin, capable of withstanding outdoor environmental conditions, and designed for insu-lation voltages from 36 kV to 40.5 kV.
The TPO 7x.xx transformers are designed as single-or-multiple turn transformers, with one transformer ratio, and, if necessary, with the possibility to change over on the primary or secondary side.
The number of secondary windings ranges from 1 to 4 (usually 2) depending on parameters (such as the accuracy class, short-circuit current, overcurrent factor…).
The secondary windings are used for measurement or protection pur-poses, or for special use (testing windings, “PX” class).One terminal of each secondary winding used, and one terminal of the unused, short-circuited, winding must be earthed during the transformer operation.The transformer can be mounted in any position.
The transformer body is fixed by using four screws. For ease of han-dling and assemblythe transformer is supplied with suspension lugs.
The secondary winding is led out into a cast secondary terminal board covered with a sealable cover.
