摘要：
In this paper are described the design and application of an inductive magnetic sensor based on nanocrystalline alloys. The sensor is adjusted for measurement and monitoration of currents with intensities from some microamperes to miliamperes. Its functional behaviour, performance and a specific application are described. One of the biggest advantages of this current sensor is its non-invasive characteristic, it means, is not required any direct contact with the circuit that is being monitored. It becomes appropriated for diverse applications where this requirement is necessary. An example of this sensor application is the metal oxide surge arresters leakage current monitoring.
