The SCT4xxx differential current transformers were designed for detecting differential currents (earth fault currents) type A. A differential current measurement can already detect very low error currents as well as various leakage currents. Continuous monitoring is necessary to be able to separate these from each other. This allows early detection of changes that may be indicative of degenerating insulation. The SCT4xxx differential current transformers thus enable condition-based maintenance and save operators the increased costs of previous blind maintenance intervals.
