WebSep 25, 2024 · However, the caution is appropriate insofar as the sensitivity of this method is much less than other ground fault detection methods, due to internal CT saturation and the inductive characteristics of the sensing device connected to the current transformer. Many of these combinations required actual component testing to predict the pickup point ... Webcircuitry provide for precision ground-fault detection. The low VOS offset-sense amplifier allows direct coupling of the sense coil to the amplifier’s feedback signal. This eliminates the large 50/60 Hz AC-coupling capacitor. The internal delay filter rejects high-frequency noise spikes common with inductive loads. This decreases false ...
