Current transformers – AGE

These transformers are used to seperate measuring and protection equipment from high voltages and to transform the currents measured to the values required by the measuring and protection equipment.

These transformers are produced in compliance with IEC, VDE, ANSI, BS and other standards.

* Because of bar-type high-voltage winding, AGE transformers are intended for use in cases where rated primary currents exceed 600 A and can be with secondary reconnection.
* Cores used in current transformers are made either of quality cold-rolled grain-oriented magnetic steel sheets or high-quality soft magnetic material (Mumetal) depending on the required accuracy class and the primary current.
* Low voltage winding is uniformly distributed around the circular core.
* The conductors used for windings are made of electrolytic copper.
* Main insulation of these instrument transformers is an epoxy compound based on cycloaliphatic resin for outdoor installation, cast in high vacuum and with superior dielectric and mechanical properties.
* Primary terminals for rated currents 600 to 3500 A are shown in drawings I-IV. They are corrosion protected by galvanic nickel plating.
* Secondary terminals are made of stainless steel screw M8 (inox) and are placed inside the terminal box. The terminal marked with symbol must be properly earthed. Terminal boxes is equipped with cable gland for cable of 16 mm diameter.
* The earthing screw (red marked) on the lower part of transformer has to be earthed.
