The world's most trusted PCB design system. A capacitor circuit simulation is intended to examine the transient response and frequency domain response of a capacitor circuit. While the time constant and transfer function are normally the most important points to calculate, there are other important quantities that can be determined.
In a capacitor simulation, there are some specific points that should be calculated: PCB design applications like Altium Designer will include a complete set of circuit design tools in a schematic editor, allowing designers to perform any type of circuit simulation, including capacitor simulations.
Capacitor bank rack voltages are tiered but are shared among all units on each rack, which can test dielectrics: this paper presents simulation models to explore distributions of dielectric stress which can result from such arrangements.
The more evenly capacitor elements are matched, the more evenly are stresses on dielectric shared, and as increased volt-age stresses accelerate dielectric aging, consequently the less likely any single element is to experience disproportionate stresses such that it would be at risk of premature failure.
Capacitor banks are typically configured in balanced arrangements, where standards require each unit to be measured individually at commissioning and positioned to best balance a neutral or bridge.
In filtering arrangements (Figure 1), capacitor banks attenu-ate characteristic harmonics which arise from power-electronic converter interfaces. Such assets are susceptible to 'cascading' degradation and comprise many individual units, making them difficult to maintain.
