Abstract
The invention relates to a magnetic field measuring device and a method for detecting a localization current in a branched AC power supply system. Furthermore, the invention relates to a use of the magnetic field measuring device according to the invention as a device for detecting a test current for an insulation fault localization system. By combining two current sensors having a different magnetic field measuring sensitivity and a different magnetic field measuring range, it can be achieved that a reliable detection of localization currents in insulation fault localization systems is possible by means of a constructionally easy and cost-effective realization, in particular as retrofitting in existing systems.
