Spark discharge monitoring system and spark discharge detection device

Abstract

This system provides highly accurate monitoring of spark discharges based on the time-dependent changes in spark size. [Solution] The spark discharge monitoring system comprises a receiving unit, a control unit, and a display unit. The receiving unit receives spark information. The control unit acquires the time change of the spark number based on the spark information, corrects the spark number based on operating data including at least the field current, and displays the time change of the corrected spark number on the display unit.
