Partial discharge testing on power transformers

Показать описание
Learn about the importance of partial discharge testing (PD testing) on power transformers. Partial discharge is a major cause and reliable indication of developing insulation defects in power transformer bushings and windings, which can cause their eventual failure and costly outages. PD testing is an effective diagnosis method used to detect and localize insulation defects and to evaluate the overall insulation condition and risk of failure in power transformers during factory testing, site acceptance testing (commissioning), as well as in-service troubleshooting for effective maintenance planning. For highly reliable, industry-standard PD testing on power transformers, OMICRON recommends the MPD 800 universal partial discharge measurement and analysis system.

Good day sir, if online measurement is possible.. can I ask if Mathematical model of PD in transformer is possible?
