Silent Threats, Visible Signs: How Partial Discharge Measurement Systems Protect the High Voltage Measuring Equipment Market
In high voltage electrical equipment, the most dangerous defects are the ones that announce themselves softly—a faint crackle, a microscopic spark within an air pocket of solid insulation, a glow on a contaminated surface. This phenomenon is partial discharge (PD), a localized electrical breakdown that does not immediately bridge the entire insulation but progressively erodes it over...
