Fluxgate DC Earth Leakage Current Sensor

Current - Output Fluxgate

The current-output fluxgate may be tuned by using a serial capacitor. Such tuning increases the sensor sensitivity in the situation when the pick-up coil has a low number of turns. We achieved a signal/feedthrough ratio improvement by a factor of 5. The measured parameters fit the simplified theoretical model within 20% deviation

Micro-fluxgate sensor with closed core

Micro-fluxgate sensor with symmetrical core on both sides of the planar rectangular excitation and pick-up coils has substantially improved parameters compared to its single-core predecessor. Almost closed magnetic path for the excitation field allows much deeper saturation of the sensor core, which reduces the perming effect, hysteresis and noise. Perming of max. 5 μT for 6 mT field shock, 28 ...
