Abstract

The present embodiments relate to a measuring apparatus and an associated measurement method. The measuring apparatus is installed on a line and includes a sensing unit having a first and a second voltage divider for producing a first and a second measurement signal with a measurement transducer. The first and second measurement signals are each forwardable via a measurement line directly to a signal transducer. The signal transducer is supplied with power via a supply line by being switchably connected to the measurement transducer.
