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…
