What is High Voltage Bushing Diagnostics about?
Advanced diagnostic tests can identify issues in high voltage bushings. Capacitance and dissipation factor measurements every 10 years after installation and every 5 years depending on the results can detect problems. Resin bonded paper bushings from 1913-1974 and oil impregnated paper bushings since 1960 require special attention as the paper insulation ages over time. Measurement of capacitance, dissipation factor, and partial discharges at different voltages and frequencies can identify defects like mois
