PCB Rogowski Coil sensor by using Saw blade pattern for arcing fault detection
Journal of Physics: Conference Series, 2023 Abstract Rogowski is a special current transformer and has been categorised as a low-power stand-alone current sensor. This sensor is designed by using a Saw blade pattern with 50 turns and 100 turns. This number of turns will impact the increment of the sensitivity of the sensor.
