    • Lowering the Limites for Ground-Fault Detection

      The limit to practical low-level ground-fault protection in industrial electrical systems is a function of physical parameters. Current sensing is the best method to detect and locate ground faults; however, system capacitance, unbalanced loads, current-sensor limitations, and harmonics affect current measurement and limit the lower level of practical ground-fault detection.
