Product Description

Introduction:
Anti-resonant voltage transformer, with 4 windings, nominal voltage 500 kV, from transformation ratio 500: √3 / 0.1: √3 / 0.1: √3 / 0.1kV, with
contact terminals for connecting three wires in phase. Rated voltage of the secondary windings: Winding No. 1 for power supply of relay
protection and automation circuits (connection according to the "star with zero" scheme) - 100 /: √3V Winding No. 2 for power supply of
metering and electrical metering circuits (connection according to the "star with zero" scheme) - 100 /: √3V Winding No. 3 additional
(connection according to the scheme  "Open delta") - 100V Accuracy class 0.2 / 0.2 / 3

Technical indicators 4.1. Rated secondary load of the protection winding (10 PR) - 20VA. The rated maximum current ratio for the protection
winding (the ratio of the max short-circuit current to the rated primary current of the CT, at which the CT error is less than 10% at a given
secondary load) is 30. The intrinsic resistance of the current transformer is not more than 36 ohms. The rated secondary load of the
measurement and metering windings is 30VA. - Wind head - V = 29m / s. - Ice-covered area - II (10 mm) - Minimum temperature - 25 0
FROM - Maximum temperature - +50 0 FROM - Seismic - 7 points on the MSK-64 scale - Equipment insulation - II * (specific creepage
distance 2.25 cm / kV) in accordance with GOST 9920-89
