Detection of Partial Discharge in Switchgear Under Different Humidity Using Transient Earth Voltage and Ultrasonic Method
Aiming at the limitation of the existing detection method of partial discharge(PD)in switchgear
a composite PD detection method is presented by combining transient earth voltage and ultrasonic method.The PD in a switchgear is detected with the present method in different artificially simulated humidity conditions
the PD detection results are analyzed
and the insulation of the switchgear is evaluated.Suggestions
such as setting infrared heater
adopting hydrophobic material for the insulation panel
are offered to improve the insulation condition of a switchgear.
