Consulting for fault location using FLISR (Fault Location, Isolation and Service Restoration):

·       Fault location strategy and implementation for distribution system

Distribution System Fault Location

Ratan has contributed significantly to the research of Distribution System Fault Location through his doctoral work at the University of Saskatchewan, Canada during the 1990s which created the foundation for FLISR system. This work is highly cited in academic and in industry publications.

Ratan collaborated with his ABB colleague for the improvement of the fault locator algorithm which has been implemented in ABB’s distribution IEDs, resulting in a  patent on Fault Locator for Radial Subtransmission and Distribution Systems.

Transmission Line Fault Location

Ratan has developed a software for transmission line fault location which has been implemented in a digital fault recorder in the late 1990s.  Ratan has collaborated with his ABB colleague to publish a review paper on Transmission and Sub-transmission Line Fault Location.
