Latest Patents

One of his latest patents is titled "Fault locator for radial sub-transmission and distribution systems." This invention presents an improved method for locating faults associated with conductors in electric power systems. The method involves detecting a fault and determining the availability of pre-fault data to compute load impedance, which aids in estimating the fault location. If pre-fault data is unavailable, the method utilizes data from memory locations to ensure accurate fault location estimation.

Another significant patent by Ratan Das is the "Current based frequency tracking method and apparatus." This method measures the fundamental frequency of a power system by sampling voltage and current waveforms. It includes criteria for determining whether the fundamental frequency can be measured using voltage or current samples. If neither is possible, the method relies on previously measured values to maintain stability in frequency tracking.
