Current Transformer ( ASTA Certified )

Frequency                   :           50/60Hz

DielectricStrength      :           2,500V r.m.s for 1 min

Temperature              :           AmbientRange 40C to + 70C

Overloads                   :           As Bs7276 and IEC 44-1

Designed to meet the highest standards in accordance to BS7276 and IEC44-1 ERWIN CTs have performance as follows:

The high gradesilicon steel core is annealed, and then insulated with H.D. Polyethylene caps. The secondary winding is torridly wound by high precision machinery. MR and PR SERIES CTs, the PEW coated windings are then covered with elephantine paper and double lapped with non adhesive insulating tape, as for the FR SERIES, the construction is the same with the MR & PR series except that it is double lapped with fibre-tape and then varnished. For encapsulated type, Model MSQ,NSQ, RQ & CRQ CTS, has been developed to meet the requirement of modern electrical installation. This range of current transformer is very compact and robust and can be used for a wide range of current measuring purposes. It is designed for the use with busbar of cable conductors. Moreover, Epoxy type current transformers are also available now.

Current transformers for measuring and protective applications.
