There are two most common derating parameters: voltage (that may include hidden current limitation) and temperature The derating factors are typically in "OR", "whatever is greater" logic relationship, so if the voltage derating rule says 20% and due to the temperature you have to derate 30% as well, "whatever is greater" condition applies – …
An online calculator for calculating the voltage of a capacitor helps you to calculate the voltage U of flat (parallel-plate capacitor), cylindrical and spherical capacitors and gives a detailed solution. Units of measurement can include any SI prefixes. The calculator automatically converts one SI prefix to another.
A three-phase motor has 100kW real power load at operating at 0.7pf, we need to improve the power factor to 0.96. Let we calculate the required reactive power in kVAR or capacitor bank to be connected across the motor? Here, PF 1 = 0.7. PF 2 = 0.96. Required capacitor bank = 100 x tan (cos-1 (0.7)- cos-1 (0.96)) = 72.85 kVAR.
