Pratap Mysore - Founder, Pratap Consulting Services, has over forty years of experience in the power system industry. His expertise is in the areas of substation protection and control design, transient studies and maintenance and commissioning, developing Protection philosophies for utilities, equipment specifications and testing standard documents. He has been retained as a consultant for on-call services by several utilities for technical support of transient studies, settings review, training and disturbance/ event analysis. He is the Chair of the IEEE Power Systems Relaying and Control Committee (PSRC) and has actively participated in IEEE standards development projects. He is also a member of the capacitor subcommittee of IEEE PES T&D committee responsible for developing IEEE documents related to shunt and series capacitor banks.
As an adjunct professor at the University of Minnesota, he taught a graduate level course in power system protection from 2011 to 2015. He was involved in developing media modules for the Consortium of Universities for Sustainable Power (CUSP) as part of Department of Energy (DOE) sponsored program led by University of Minnesota. He is a member of the planning committee of Western Relay Protection Conference and has presented tutorials and papers at regional power systems and relay conferences in the USA. He has Bachelor’s and Master’s degrees from Indian Institute of Science, India and is a registered Professional Engineer in the state of Minnesota.



The presentation covers the effect of degree of compensation and point on wave switching on the DCZ phenomenon and discusses various mitigation methods. The presentation also discusses protection and automatic control practices that can be employed to minimize DCZ transient effects, on the equipment, to successfully clear faults.
