Abstract

A voltage transformer with a voltage divider for measuring the voltage in medium high voltage and high voltage installations have a combined arrangement of an ohmic divider resistor and elements for compensating ambient electromagnetic effects, and the divider resistor is made of one peace with a measuring resistor and with taps, wherein at least one tap is connected with at least compensation element.
