Product description

Voltage instrument transformers VPT 25 are single-phase transformers. They are designed for the use in the high voltage systems. They are designed for measuring and protection of high voltage distributing equipment for outdoor design. They are suitable for supplying of drives of remote-controlled section switches.

The accuracy classes for measuring winding are 0.2, 0.5, 1, 3, for the securing winding of 3P and 6P. The transformers satisfy required accuracy class at intervals from 25% to 100% of rated load.

Magnetic circuit of voltage transformers VPT 25 is made of oriented transformer strips in the shape of "C" of core. The outlets of primary winding are brought out by the means of bolts M10. For contacting them we recommend use conductors of maximum diameter of 6 mm2 and terminal ends by reason of suspensionof dynamic forces and vibrations within the system.

ATTENTION! The isolators must not be pre-stressed mechanically in the direction away from the body of transformer during the other way of contacting.

All active parts of transformers VPT 25 are compound-insulated with epoxy-mixture resistant to the external effects (UV radiation, humidity, etc.) This material performs both the electrical insulating and the mechanical functions.
