The work presented here deals with the effects of a simple surge absorber composed of an ordinary choke coil, and connected in series with the line ends of a power transformer. The study includes the effect of such absorbers on the wave form of the incident surge, and consequently on the voltage distribution along the high voltage transformer windings. Moreover, a sample set of calculations has been performed to find out the way, the absorber constants, and the transformer simulating capacitor capacitance, contribute to those effects. These calculations are included in the second part of the work.
