Voltage transformers – VPV

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.

* Cores used in voltage transformers are made of quaity coled-rolled grain-oriented steel sheets. All cores used in transformers are thermally treated.
* Low and high voltage windings are designed as multilayer windings. They are are wound of lacquered copper wire. The insulation between layers is foil with insulating paper on both sides.
* The main insulation of voltage transformers is an epoxy compund based on cycloaliphatic resin for outdoor installation, cast in high vacuum and with superior dielectric and mechanical properties.
* Primary terminals are made of stainless steel screw M10 (inox).
* 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 box 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.
