“…Thus the electric field enhancement in defects such as cracks is much larger compared to traditional insulation materials, and can lead to partial discharge even if the applied external field is below the dielectric strength of air. For BaTiO 3 multilayer capacitors with relative permittivity ε r ¼ 60 and thickness of 50 mm, the PD can be initiated by voltages below 200 V [7]. For bulk BaTiO 3 ceramics with thickness of 1 mm, the PD inception electric fields were reported to be below 1.5 kV/mm [8].…”

Although piezoelectric ceramics are widely used, the structural reliability of these materials in long‐term service is still a concern. In this study, a nondestructive method for assessing material strength reliability using partial discharge (PD) tests is proposed. The PD inception electric field and the flexure strength are both controlled by the defects in the ceramics which suggests that the PD test can be an alternative nondestructive method for evaluating the structural reliability of piezoelectric ceramics. PD and four‐point flexure tests were carried out on piezoelectric ceramics. The influence of the PD test on samples was investigated by comparing the microstructure and electrical properties before and after the PD test. Samples which were not PD tested were also fractured and compared. It was found that no strength degradation was caused by the PD test. Weibull analysis revealed a correlation between the distribution in values for PD inception electric field and flexure strength.
