Designs for optional
Features
1) More ratios to ensure good accuracy
2) 5 to 3200A current transformer design
3) Used for precision measurement of AC current or calibration of instrument current transformer
4) Can be installed on a bus bar can be used with a primary conductor consisting of turn numbers
5) Designed with a tapped primary & secondary windings to ensure a large number of ratios over
a range 5 to 3200A (or more as option)
6) Adopting “two stage principles” to ensure excellent accuracy and also allow to run long leads between
CT and load but not degrading CT accuracy.
7) Adopting advanced design technology to ensure that it can be used in severe magnetic environment
and also not affected by position of primary conductor in the hole or in the location of return conductor
8) With facility to test the performance of CT and verify its own accuracy.
9) CT ratio selection switch is optional and if customer need, it can be provided by adjust the design structure,
then can select mentioned CT ratios but no need changing secondary.
Note:
1) Also can offer standard current transformer integrated with source (3200A CT with 4000A & 8.8KVA source;
2000A CT with 2400A & 8.8KVA source)
2) Photo design mentioned in the brochure is as a reference, final design possibly will have change after
customer inform special & optional requirements.
3) If choosing bigger one design, customer can reduce a lot of time when applying turns.
