<p>1. A high voltage measuring device having a capacitive voltage divider in a container (1) filled with insulating gas, in which the high voltage capacitor consists of a conductor (3) which is at a high voltage, and a measuring electrode (4) which surrounds said conductor, and the low voltage capacitor consists of the measuring electrode (4) and a low voltage electrode (5) which surrounds said measuring electrode, characterised in that the measuring electrode (4) is in the form of a ring having a predetermined width ; that the low voltage electrode (5) is in the form of a further ring having a width which corresponds approximately to the width of the ring of the measuring electrode (4) ; and that the measuring electrode (4) is connected to at least one active voltage divider (7, 11, 13), at the outlet of the amplifier (11) of which, a voltage appears which is proportional to the high voltage.</p> |
