Abstract

In this paper, a method is presented for measurement of power frequency magnetic fields due to distorted sinusoidal currents in power systems. The proposed method is an integral approach and consists of a multi-rate digital signal processor, an adaptive filter and an overlap processor. In field test, actual test results are accomplished by a standard area-type measurement setup to identify and characterize magnetic fields distribution of a 69 kV SF₆-gas insulated substation (GIS) using the proposed method
