Some force circuit elements 2.1. Resistance, Inductance and Capacitance (RLC) With PSIM, discrete R, L, C elements or an RLC branch can all be described with defined initial conditions (current across L, voltage across C). In addition to the symmetric threephase circuit, the RLC branch is also described with the initial conditions defined as zero by the symbols “R3”, “RL3”, “RC3” and “RLC3”.
