Description
To diagnose electric power apparatus under operation, to detect partial discharge (PD) which refers predictive phenomenon on insulation deterioration of electric power apparatus is useful. An acoustic emission (AE) and an electromagnetic wave sensor techniques are widely accepted for the detection of PDs. However, the relationship between the intensity of signal and electrical charge due to PDs is not well investigated. We here focused on diagnosing vacuum circuit breakers (VCBs), and examined to detect PDs in a cubicle. The PDs were detected by AE and electromagnetic wave sensors, and their sensitivities were evaluated. Based on the results, we discussed an optimal detection method for detecting PDs in a cubicle.
