Latest Patents

One of Tobin's latest patents is titled "Optimized Transformer Protection." This invention introduces a method for determining an optimized time-current characteristic (TCC) operating curve for electronic interrupting devices that protect distribution transformers. The approach involves creating a TCC transformer curve, which identifies allowed operational current levels once the transformer is stabilizing, and establishing an optimized TCC curve that is a predetermined percentage above the normal operational curve. This innovation is crucial for the efficient functioning of transformers, ensuring they remain within safe operation limits.

Another significant patent is focused on the "Transformer Internal Fault Reclose Block." This fault detection system prevents a recloser from reclosing if a fault is determined to be internal to a transformer. The recloser performs its functions based on overcurrent detection while utilizing a light sensor aimed at the transformer to detect fault events. In cases where overcurrent is detected but no fault event is confirmed by the sensor, the recloser strategically avoids reclosing, thereby protecting the transformer from potential damage.
