| 摘要 | 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. | ||

| 主权项 | 1. A method for impressing a measuring-signal voltage on a power supply network comprising the steps of: providing a generator signal; generating sampled values by alternately sampling the generator signal by two sample-and-hold elements to alternately produce a first pulse sequence and a second pulse sequence; and inductively transmitting the first and second pulse sequences separately into the power supply network to induce partial voltages, wherein a secondary-side measuring-signal voltage is formed in the power supply network by adding the induced partial voltages. | ||
