して容量分圧器が用いられている。(Prior art) Conventionally, wire-wound instrument transformers and resistance voltage dividers have been widely used as devices to measure the voltage of high-voltage devices such as power generation and transformation equipment and laser oscillators. Therefore, there is an increasing need to simultaneously measure not only the voltage at the commercial frequency of 50 Hz or 60 Hz, but also phenomena in the high frequency range from several HH2 to several tens of fHz. The phenomena in question here include a disconnector surge phenomenon occurring in a GIS tank, a laser oscillator discharge phenomenon, and the like. These phenomena occur in several nanoseconds or tens of nanoseconds. A capacitive voltage divider is used to observe objects in which the phenomenon occurs for a very short time.
