Latest Patents
Yuji Urabe holds a patent for an insulation degradation diagnostic device. This innovative device comprises several components, including a current transformer, amplifiers, high-pass and low-pass filters, and a discharge judgement section. The current transformer detects the current flowing through a grounding conductor and has a filtering function with an attenuation of -60 dB or less. The first amplifier amplifies the current signal, while the first high-pass filter removes low-frequency components. The low-pass filter then eliminates high-frequency components from the signal. The second amplifier amplifies the filtered signal to a predetermined level, and the second high-pass filter extracts signals corresponding to discharge currents caused by partial discharges. Finally, the discharge judgement section assesses whether a partial discharge has occurred in a cable based on the extracted signal.
