Capacitive load elements use industrial grade capacitors that store electrical charge. Because these devices store surplus charge and resist changes in voltage, they cause current to peak before voltage during electrical cycles. As a result, capacitive load bank elements provide a leading power factor, and are often used to adjust power factor to

The constant phase element (CPE) is a capacitive element with a frequency-independent negative phase between current and voltage which interpolates between a capacitor and a resistor. It is used extensively to model the complexity of the physics in e.g. the bioimpedance and electrochemistry fields. There is also a similar element with a positive phase …

a certain degree, the element is called a constant phase element (CPE) that also includes a normal capacitor when n = 1, and its impedance is expressed below [5], eq (1) where ω is angular frequency, Y 0 and n are the char-acteristic parameters of the CPE. Therefore, instead of a capacitor, a CPE is very frequently used in analy-
