Abstract :
The problems of measuring the characteristics of transient voltage and current waveforms occurring in high-voltage power systems are discussed, and the analog recorders that have been used in the past are reviewed. The theory of operation of digital recorders is described, and sources of recording errors are examined. Applications of digital oscilloscopes to measuring switching surges and partial discharges and to high-voltage impulse testing are discussed.<>
