Abstract
A method and device for impressing a measuring-signal voltage (U) on a power supply network in which a generator signal (Usig) is alternately sampled by two sample-and-hold elements (20, S1, S3), the sampled values are alternately allocated to a first pulse sequence (P1) and a second pulse sequence (P2), the pulse sequences (P1, P2) are separately inductively transmitted and the secondary-side measuring-signal voltage (U) is formed by adding the induced partial voltages (U1, U2) together.
