Design & Testing

DESIGN:

CT is a Customer specific product, characteristics of which depends on the system parameters and the protection schemes being followed. Besides, for CT being used in Power Transformers and Reactors dimensional constraints because of space limitation jn tank or the type of bushing being used, is a major factor effecting the Design of CT, Virtually each and every CT therefore is unique in it self.

Within house technical capabilities we can design CTs for both metering and Protection applications. Our In-house developed Computer programme helps us in optimizing the design with in the customer’s specified parameters.

 

TESTING OF CURRENT TRANSFORERS:
We, at AU Electro machines, are well equipped with in house test facilities to conduct all  routine and type tests (Except Special test) on  all metering and protection class CTs as per relevant Standards viz. IS 2705, IEC 60044, Australian Standard, BS 3938, or IEEE.

Preliminary Inspection / Test.
After having received the CTs, at plant /site,should first be checked for any transport damage.
If necessary carry out inspection/test and confirm with the tests certificate supplied.
Continuity of secondary leads and their marking/s must be carefully checked.
