Consulting for fault location:
location strategy and implementation for distribution system
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.
This work is highly cited in academic and in industry publications and
considered to be one of the early work in this area.
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.
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
