Voltage Sag Source Location: Case Study in Zambian Grid

Paper i proceeding, 2007

This paper describes a case study to find the location of the voltage sag source at a petroleum industry where sags are causing undesired trips on critical loads. The network that supplies this industry is operated by basically two transmission and distribution utilities. Therefore, finding the location of the disturbance source is a first step in mitigation and decisive in allocating responsibilities.
