Current Sensor Based on Rogowski Coil.
We have built several Rogowski coil current sensors for measuring currents in non sinusoidal systems. In this paper we present the sensor and his behavior. We have built a generator of pulses in order to test it and we compare the results between two types of coils (flexible and Printed Circuit board PCB designed) and the linearity for measuring ...

The relationship between power of arc discharge in transformer oil and peak value of the shock wave
Abstract Since 2018, there have been seven incidents of explosions and fires in ultra‐high voltage transformers in China, which are caused by internal arc discharge in transformer oil. Various pressure measurement experiments have been conducted to explore the laws of discharge pressure. However, differences in experimental conditions, discharge energy,
