With a total of 5 patents, his work focuses on enhancing the safety and efficiency of electrical systems.
Latest Patents
One of Povh's latest inventions is an earth contact monitoring device for a polyphase three-phase filter. This innovative monitoring system detects earth contact of at least one phase in a polyphase network. Each phase is connected by a capacitive-inductive filter to a neutral node linked to earth. The system utilizes an induction current transformer to detect the current flowing from the neutral node to earth, producing a signal responsive to the earth current. The output signal is processed through a low pass filter to suppress harmonics and is rectified to generate a direct current voltage signal. A fault indicating signal is triggered when this voltage exceeds a predetermined value.
Another significant patent is a monitoring system for the capacitor batteries of a three-phase filter circuit. This system monitors the capacitor batteries formed of multiple parallel legs, each containing sectional capacitors connected in series with fuses. In a three-phase system, these capacitor batteries are arranged in a Y-circuit configuration. The system evaluates variations in the current flowing from the Y-circuit node to the reference potential to identify defective sectional capacitors. Rapid variations in the Y-circuit node current trigger fault signals, minimizing false indications caused by temperature changes.
