Square D 460R Voltage Transformer

Manufacturer: Schneider

Voltage Transformers (VT) Circle Diagrams are provided as an easy method for determining accuracy at any burden and power factor. The radial lines represent different power factors for the burdens and the concentric circles represent burden amount in Volt-Amperes.

VT accuracy at a specific burden may be determined by choosing the appropriate power factor line that represents the power factor of the actual burden, then extending outward in the radial direction to the appropriate volt-ampere level. Note that the concentric circles represent proportional Volt-Amperes that increase in value as you extend outward.

The Ratio Correction Factor and Phase Angle error for this Burden may be taken from the ordinate and abscissa of the circle diagram.
