Aside from KVA rating, what is another critical rating for all capacitors?

The importance of voltage as a critical rating for all capacitors lies in its role in ensuring the safe and effective operation of capacitors in electrical systems. Capacitors have a specified voltage rating that indicates the maximum voltage they can handle without risking breakdown or failure. Exceeding this voltage can lead to dielectric breakdown, resulting in potential damage to the capacitor, failure of the electrical circuit, or even safety hazards.

Having the correct voltage rating is particularly significant because it helps in selecting capacitors that will operate reliably within the specific requirements of a given application, ensuring that voltage levels do not exceed what the capacitor can safely manage. In conjunction with KVA ratings, voltage ratings help electrical professionals choose appropriate capacitors for load management, power factor correction, and reactive power compensation in various systems.
