CORONA DISCHARGE DETECTION PROBE AND DETECTION SYSTEM INCLUDING THE SAME

摘要

PURPOSE: A corona discharge detecting probe and a detecting system with the same are provided to effectively detect a corona discharging signal, thereby effectively detecting a corona discharge signal. CONSTITUTION: A corona discharge detecting probe(100) detects a corona discharging signal in stator winding of a stopped generator. The detected corona discharging signal is transmitted to a measurer(400) through a filter(200) and an amplifier(300). The corona discharge detecting probe is an inductive coupling probe. An inductor is made of a ferrite core and an inductor coil. A foam functions as an external cover for electrical insulation. A power supply terminal is protruded from the form. The ferrite core is made by cutting a ring shaped ferrite core.
