What is Electromagnetically induced current and Electrostatically induced Current in Earthing switch

Worawut Sae-Kok, Global Product Marketing Manager Disconnectors

ABB's answer

There are clear definitions in IEC 62271-102 (2011) in Annex C: Induced current switching by earthing switches:

Electromagnetically induced current: Inductive current that an earthing switch is capable of switching when it connects to and disconnects from earth one termination of a de-energized transmission line, with the other termination earthed, and with an energized line carrying current in parallel with, and in proximity to, the earthed line

Electrostatically induced current: Capacitive current that an earthing switch is capable of switching when it connects to or disconnects from earth one termination of a de-energized transmission line, with the other termination open, and with an energized line in parallel with, and in proximity to, the earthed line
