Overview 1.1 Scope This standard applies to capacitors rated 216 V or higher, 2.5 kvar or more, and designed for shunt connec- tion to alternating current transmission and distribution systems operating at a nominal frequency of 50 Hz or 60 Hz, within the guidelines of IEEE Std 1036™-19921. 2.
4. Service conditions 4.1 Normal service conditions Capacitors 2400 V and higher are expected to operate as indicated in the revision of IEEE Std 1036-1992, in effect on the date that the capacitor is manufactured.
Chart1: CAPACITOR MARKING CODE STANDARDIZED BY THE ELECTRONIC INDUSTRY ALLIANCE (EIA) The voltage rating on a capacitor indicates the maximum voltage it can safely handle. This parameter is ensuring safety and performance, as it prevents over-voltage failures that can damage both the capacitor and the surrounding circuitry.
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.
The maximum voltage for capacitor calibrations is presently 170 kV at 60 Hz. The restrictions are imposed by the supply transformer and not by limi- tations in the measurement instrumentation. There- fore, this constraint should not be considered time invariant and clients should contact NIST about present physical limitations.
The internal insulation assembly shall assure that the capacitor will meet the requirements of 7.2.1 in order to demonstrate that the insulation is adequate for the highest ter- minal-to-case (or terminal-to-terminal) voltage in the intended equipment.

Capacitor Basics: How do Capacitors Work? | CircuitBread
Smooth power supplies. As capacitors store energy, it is common practice to put a capacitor as close to a load (something that consumes power) so that if there is a voltage dip on the line, the capacitor can provide short bursts of current to resist that voltage dip. Tuning resonant frequencies. For electromagnetic systems, antennas, and ...

23.2: Reactance, Inductive and Capacitive
For capacitors, we find that when a sinusoidal voltage is applied to a capacitor, the voltage follows the current by one-fourth of a cycle, or by a (90^o) phase angle. Since a capacitor can stop current when fully charged, it limits current and offers another form of AC resistance; Ohm''s law for a capacitor is [I = dfrac{V}{X_C},] where (V) is the rms voltage across the capacitor.

Capacitor Voltage Ratings And Dielectric Breakdown
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 ...

To reduce voltage dependence, a 300 kV standard capacitor with three cylindrical electrodes was proposed by the National Bureau of Standards (NBS) . Nevertheless, this type of standard capacitor is mainly used within high-voltage halls due to the problem of its external insulation structure, and is therefore not employed in this design.
