In this e-lesson you will learn why the application of online PD monitors on HV bushings is beneficial to improve your condition assessment capabilities. To achieve this, online PD monitors must be properly designed to provide meaningful and reliable information, as it will be explained in the lesson. Real cases on both RIP and OIP bushings will be shown to demonstrate how the correlation between PD and leakage current can help failure mode identification.
