Runway lights at the airport are 1-5 km in length, which always connected in series so the pilots look the same bright lights from the beginning of runway until the end of runway. The same bright lights will be on if runway lights connected in series and every lamp obtains the same current flow. The device used to manage every runway in receiving the same current is Constant Current Regulator. Each light is installed a transformator by comparing of primary winding : secondary winding is 1:1[1] so if there is a while other lights that connected in series are “ that will be analyzed how it works with series resonant principle. It can be proven that the basic CCR briefly connected then the magnitude of current is constant, although it is added by compensator, it is not a matter how much the value of load resistance (runway lamp) will still evoke current load. Compensator will carry out the best function if its reactance is as great as reactance. By using current loop and Gaus Jordan methods have found the similarity which reveals the relation between the current with load and can be stated that is not a matter how the load resistance is, will still flow the current load at constant value. Therefore, Constant Current Regulator has changed the constant voltage power supply to be a constant current power supply [1]. The aim of this paper is to define to the cadets about the application of the series resonance theory (voltage resonance), a high voltage producing from this series resonance will be flowed into electrical circuit at runway lights with constant current in accordance with the desired brightness. The learning kit for cadets is a series resonant experiments with static renance circuit with an efficiency up to 90 percent.
