Acoustic Emission Diagnostic and Monitoring of Power Transformers
Power transformers account for the largest portion of capital investment in transmission and distribution substations. Failure of a single power transformer carries a multimillion-dollar impact with a build or replacement timeline of18-24 months. Yet 53 percent of transformer failures are preventable. But what if there was a way to protect that substantial investment while safeguarding…
PowerPAC™: Acoustic Emission Testing Technology Packages
PowerPAC™ is a Technology Package for detecting, locating and assessing not only partial discharge in power transformers but also thermal faults by utilizing Acoustic Emission technology. Transformers are instrumented with AE sensors covering both the tank and the LTC compartment (if one is present). In addition, other sensors (used to monitor pump current, fan current, load…
