Novel method for selective detection of earth faults in high impedance grounded distribution networks

An elementary and reliable detection of earth faults in impedance grounded networks results in considerable benefits for the utility both in terms of outage duration and personal safety. This report describes an entirely new, only current measuring method; a method, which fulfils the standards of cost efficiency and reliability. Despite the seeming simplicity of the approach it is also demonstrated that it is an excellent method to detect arcing cable earth faults.
