Simulation of impulse current generator for testing surge arresters using frequency-dependent models

The object of research is the equivalent circuit an impulse current generator designed for testing surge arresters. Calculation parameters when discharging a capacitor bank to complex nonlinear load difficult task analytical solution. Until now, application arrester frequency-dependent models was limited problems overvoltage computation. Surge can predict residual voltage with high accuracy. This reason consider that be used calculating main generators physical arresters.
 determining required getting discharge given waveform and amplitude in scheme solved using simulation.
 article presents results studying processes circuit. In dynamic model as model. For this, path drawn up. elements (including number capacitors their charging voltage) are determined, which necessary standardized amplitude. determined arresters three different classes. It found relative error between terminals does not exceed 3 %.
 work contributes further development simulation expansion scope models. As result performed, possibility shown. performed relevant due fact have become tool protecting insulation electrical network equipment against external internal overvoltages
