A METHOD AND A DEVICE FOR VOLTAGE MEASUREMENT IN A HIGH-VOLTAGE CONDUCTOR
Application 1324/CHENP/2005 published 2007-08-03, filed 2005-06-20
Measuring equipment for the purpose of forming a measured value for voltage representing an ac voltage on a high-voltage conductor, wherein the measuring equipment comprises capacitor equipment with a known capacitance for connection between the high-voltage conductor and ground potential. The measuring equipment further comprises current-measuring means for sensing a capacitor current flowing through the capacitor equipment and for forming the measured value for voltage in dependence on said capacitor current.
