Latest Patents

Ralf Hartwig holds a patent for a "Method for gas analysis of on-load tap changers." This invention relates to a method for quantitatively analyzing gases as a monitor for on-load tap changers. The general inventive concept lies in selecting particular characteristic gases that allow for an indirect association and a dimension for aging effects, excessive discharge, and/or heating of the on-load tap changer. The method involves measuring these characteristic gases formed during the operation of the tap changer in the insulating oil at specific time intervals. It also includes forming indicative quotients from the measured values of the defined gases, which allow for direct conclusions about aging effects, excessive discharge, and/or heating. Additionally, the method displays trends from a comparison of the currently derived value of each quotient to the most recently derived value for the same quotient. Warnings for aging effects, excessive discharge, and/or heating can be inferred if the corresponding quotients tend to change significantly over time or during the course of the switch changes made.
