ABSTRACT
Background/ Objectives: Power system control systems are constantly exposed to surge voltages. These surge voltages cause malfunction of elements controlled by a low voltage such as a CPU and a semiconductor. Methods/ Statistical analysis: A control circuit is constituted by utilizing a discharge element with control electrode and a surge voltage is applied to the control circuit to measure and analyze the discharge voltage that accompanies the capacity change of the current limiting element, transformer, etc. As a result, the effectiveness of the discharge device with control electrode and the control circuit was confirmed. Findings: The capacitance of the capacitor was selected as 0.01uF, 0.1uF, 1uF and the winding ratio of the transformer was set to 15: 1. Then, the impulse voltage of 500 V was injected and the discharge voltage was confirmed. The capacitor 1uF with the lowest discharge characteristic among the capacitors was applied and the test results for the winding ratio of 15: 1 and 20: 1 were confirmed. Applying a 1kV surge voltage to a GCA control circuit with a 1uF capacitor and a 20: 1 transformer, it was confirmed. Through this test, it was confirmed that GCA control circuit can be applied to high surge voltage and maintain low discharge voltage. Improvements/ Applications: In this paper, we study various characteristics of Gate Control Arrestor (GCA) with control electrode and we will use it appropriately in various industries.
