Latest Patents

Sarasij Das holds two recent patents that showcase his innovative approach to detecting turn-to-turn faults in windings. The first patent describes systems and methods for detecting turn-to-turn faults in one or more windings of various objects. This invention utilizes a differential protection algorithm to identify faults in the windings of a three-phase shunt reactor. By measuring voltage and current, the system calculates a difference value between a voltage-based parameter and a current-based parameter. A turn-to-turn winding fault is declared when this difference value is not equal to zero.

The second patent also focuses on detecting turn-to-turn faults, specifically in transformers. This system receives a set of current measurements and executes a procedure to identify faults. The procedure involves dividing a steady-state differential current value by a steady-state voltage value to obtain compensating factors. It then determines a magnetizing current amplitude indicator and compares the compensated differential current value against a threshold value. A fault is declared when the compensated differential current value exceeds this threshold.
