In this paper the construction and electrical parameters of an air core current to voltage transducer based on the Rogowski coil principle are presented. The transducer has been manufactured in PCB HDI technology with track width and track to track distance less than 100 μm. The sensitivity and the measurement bandwidth of the transducer has been presented together with considerations on the transducer...
W artykule przedstawiono rozwiązania konstrukcyjne wzmacniacza sygnału wyjściowego bezrdzeniowego przetwornika prądowego. Wzmacniacz składa się z dwóch równoległych torów. Tor pracujący w zakresie większych prądów zapewnia zakres pomiarowy do kilkudziesięciu kiloamperów. Tor pracujący w zakresie mniejszych prądów został zoptymalizowany ze względu na jak najmniejsze szumy. Cały wzmacniacz charakteryzuje...
