Influences of different excitation parameters upon PEC testing for deep-layered defect detection with rectangular sensor
In pulsed eddy current testing, repetitive excitation signals with different parameters: dutycycle, frequency and amplitude have different response representations. This work studies the influences of different excitation parameters on pulsed eddy current testing for deep-layered defects detection of stratified samples with rectangular sensor. The sensor had been proved to be superior in quantification and classification of defects in multi-layered structures compared with traditional circular ones. Experimental results show necessities to optimize the parameters of pulsed excitation signal, and advantages of obtaining better performances to enhance the POD of PEC testing.
