Spot Checks vs Online Partial Discharge Monitoring: Why 24/7 Visibility Matters

Partial discharge (PD) activity is one of the earliest indicators of insulation breakdown in high-voltage and medium-voltage electrical assets. However, PD activity can vary in activity levels based on environment and loading on the equiptment. Relying solely on periodic testing or inspections can leave critical events undetected if measured at the wrong time, increasing the […]
