System for remote measurement of current and voltage in electrical power networks has current converter at nearby measurement point in leads to remote point, impedance balancing unit

摘要

The system has a network impedance consisting of pref. a transformer and a passive connecting network between a nearby measurement point and a remote network point. A current converter is connected at the nearby measurement point in the leads to the remote point. A unit for balancing the impedance between the nearby measurement point and the remote network point is connected to secondary side of the converter. A measurement device for measuring the voltage signal and/or one for measuring the current signal is connected to the secondary side of the current converter. An Independent claim is also included for remote measurement method.
