Transformer Scope

With ITL's extensive experience and knowledge built up over 35 years we design and manufacture a wide range of protection current transformers to many international standards including IEC 60044-1,for class PX, 5P, 10P with accuracy limiting factor up to 30 but higher if required and Current Transformer Protection Classes to IEC 60044-6, incorporating classes TPS, TPX & TPY.

Also our metering range of current transformers include the following accuracies: Class 0.1, 0.2, 0.2s, 0.5, 0.5s,1 & 3.

By understanding our customer needs and expectations, our transformers can be designed for the North American Standard ANSI / IEEE C57.13, Canadian Standard CAN3 C13 M83 and Australian Standard AS 1675, for Austalian & Canadian standards please contact for more information.

A Key part of our design process is material selection and finish, as in most cases this is what the customer will see and as such many of our transformers are suitable for use in Air, Transformer Oil, SF6 Gas, Low Smoke Zero Halogen (LSZH), Tropical, Severe Tropical, Indoor & Outdoor envoronments.

Our knowledge of design & manufacture enables ITL to supply machine wopund custom ring type current transformers with inside diameters ranging from 20mm upto 1500mm. Using our manual winding capabilities allows Instrument Transformers to go beyond the 1500mm ID as long as we do not exceed a unit weight of 1000Kg due to our lifiting capacity.

We also have a range on ITI 780-786 equivalents in the form of our models M 780, M 781, M 785 & M 786 with our voltage transformers PT G3 and PT G5 either unfused, single or double fused providing a cost effective alternative.

Our engineers regularly communicate with our customers on all technical matters e.g. Core Balanced Current Transformers CBT's designed to customer applications.
