Potential Transformer in High-Frequency and mV Voltage
Shou Gang Sui, Huan Bing Gao, Cun Gen Liu · Applied Mechanics and Materials · 2013
Instrument Transformer is widely used in measurement. However, in many cases it is used in high-frequency or millivolt voltage, such as instrument transformer used in clamp meter. In this paper, an example of potential transformer in the high frequency and mV voltage is introduced, and measuring data are presented and analyzed.
