  • Page 23: Section 5 - Charging Current & Resistor Tap Setting

    The magnitude of zero-sequence charging current is determined by the line-to-ground capacitance associated with system components. The value of this current must be known to properly coordinate the Post Glover Resistors High Resistance Grounding System. In an industrial power system where the design and components are known, the charging current can be estimated with reasonable accuracy.
