Title: Innovations by Ratan Das in Electrical Fault Detection
Introduction
Ratan Das is an accomplished inventor based in Wilkes Barre, PA, known for his contributions to electrical engineering. He holds two patents that focus on advanced methods for fault detection in electrical devices. His work is significant in enhancing the reliability and safety of power systems.
Latest Patents
Ratan Das's latest patents include a "Method and system for through fault detection in electrical devices." This invention is directed towards a method and system for fault detection analysis in a power device that is operatively associated with a differential protection unit. The power device has one input side and one output side through which input and output currents flow. Signals representative of these currents are processed to verify if a fault is external to the power device. In the event of an external fault, the differential protection unit is disabled for a determined interval of time.
Another notable patent is "Dynamic energy threshold calculation for high impedance fault detection." This technique dynamically determines the occurrence of a high impedance fault (HIF) independent of load. The HIF algorithm provides the energy value for a given number of samples of the input signal, which includes phase (load) currents and/or neutral (residual) current. The input signal energy value is multiplied by a factor ranging from about 110% to about 300% to calculate a threshold energy value, which is then stored in a buffer. A HIF detection signal is generated when the energy value determined for samples of the input signal exceeds a predetermined number of calculated threshold energy values.
