The components providing isolation from primary to secondary cannot be tested while installed in the power supply without risk of damage to the unit. To make matters worse, switching type supplies use line-to-ground capacitors to reduce the EMI. When the ac hipot voltage is applied

Understanding Capacitor Voltage Ratings. Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent
