Requirement of Capacitor Banks Let us first discuss the actual requirement of capacitor bank in the power system. Actually, inductive loads such as transformers, motors, reactors, transmission networks, etc., cause current to lag behind the voltage. This increases the phase angle between current and voltage which in turn reduces the cosine of that angle. The … Read more
Capacitor Elements A capacitor element is the fundamental building block of a capacitor unit, consisting of two metal electrodes separated by a dielectric medium. Multiple elements are connected in series or parallel to form the internal circuit of a capacitor unit. To match the system’s rated voltage, several capacitor units are connected in series. The … Read more
Reactive power is measured in VAR, where V stands for volts, A for amperes, and R denotes reactive. In power systems, particularly in transmission networks, reactive power is typically expressed in megavolt-amperes reactive (MVAR), where 1 MVAR equals one million VAR. What is reactive power? The reactive power is not a useful power. This is … Read more
