This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower. This is why the different MLCC capacitor dielectric types exist, they guarantee a certain capacitance vs voltage characteristic (amongst other things)
Rule of thumb round here is that caps rated for 2x the working voltage is a good (reliable) part. You tend to find more like the opposite. A high voltage capacitor will have it's capacitance rated at low voltage meaning when operated close to it's rated voltage the capacitance will be much lower.
Operating a high voltage capacitor at lower dc voltage cause some low continuous current to flow through the capacitor, thus rendering the capacitor not behaving ideally as a capacitor. The voltage rating of the capacitor is the point at which the dielectric & insulation between the two plates starts to break down and fails.
This document does not pertain to low voltage oil-filled or direct current (DC) power capacitors. 4.1 Capacitor internal design and construction Description of internal materials, dielectric, insulation, metallization, winding methodology and filling agent.
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.
