For example, if you have a capacitor with a nominal capacitance of 100 µF and a tolerance of ±10%, the tolerance range would be: Tolerance Range (ΔC) = 10% × 100 µF = 0.1 × 100 µF = 10 µF. This means that the actual capacitance of the capacitor could vary between 90 µF and 110 µF due to the specified tolerance.
Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

Capacitors within the framework of the distribution system reduced the whole actual power loss, cost of real power loss, total cost capacitor banks, and improved the voltage profiles by compensating the reactive power.
After running the proposed optimisation algorithm for the case of 100% load level to select the optimal locations and determine the capacitor optimal sizes, the outcome leads to only two locations for capacitor placement which are buses 21 and 62 with optimum capacitor ratings of 250 and 1200 kVAr, respectively.
An X capacitor failure usually causes a fuse or circuit breaker to open. Y Capacitors: Class-Y capacitors, also known as "line-to-ground capacitors" or "line bypass capacitors," offer line-to-ground protection, which generally means that if a failure with the ground occurs, there is a risk for shock. However, Class-Y safety capacitors ...
