Latest Patents

One of Schuch's latest patents is an earth contact monitoring device for a polyphase three-phase filter. This innovative monitoring system detects earth contact of at least one phase of a polyphase network. Each phase in the network is connected by a capacitive-inductive filter to a neutral node, which is grounded. The invention utilizes an induction current transformer to detect the current flowing from the neutral node to earth. The output signal is processed through a low pass filter to suppress harmonics and is rectified to produce a direct current voltage signal. A fault indicating signal is generated 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.
