V. Jayashankar,S. Anand,T. Geetha,S. Santhakumar,V. Jagadeesh Kumar,M. Ravindran,T. Setoguchi,Manabu Takao,Kazutaka Toyota,Shuichi Nagata +9 more
TL;DR: In this paper, a new topology that uses twin unidirectional turbines (which feature a high efficiency spanning a broad range) is proposed, and it is shown that the power output from such a module considerably exceeds existing optimal configurations including those based on a fixed guide vane impulse turbine or a Well's turbine.

A twin unidirectional impulse turbine topology for OWC based wave energy plants – Experimental validation and scaling
K. Mala,J. Jayaraj,V. Jayashankar,T. M. Muruganandam,S. Santhakumar,M. Ravindran,Manabu Takao,T. Setoguchi,Kazutaka Toyota,Shuichi Nagata +9 more
TL;DR: In this article, a scale model of the twin unidirectional turbine topology was built and tested using simulated bidirectional flow, and the results from the experiments are scaled to evaluate the design features of a 50 GWh wave energy plant.
Journal ArticleDOI
Real-Time Techniques to Measure Winding Displacement in Transformers During Short-Circuit Tests
TL;DR: In this article, the authors propose new techniques for fault detection based on continual assessment during the test. They include voltage comparison, current comparison, and real/reactive power measurements, which are validated on a number of models including a voltage transformer and a distribution transformer winding.

Virtual Instrument for Lightning Impulse Tests
A. Palani,V. Jayashankar +1 more
TL;DR: In this paper, an objective formulation of the impulse analysis problem from a signal analysis viewpoint is proposed, where the winding response is quintessentially that of a deterministic network to a finite energy signal, with breakdown and partial discharge being inherently nonlinear events.
