  1. Abstract : there are only two set values ( 30, 45 ) for interior angle of the stimulated directional power relay as the protection in phase to phase short circuit fault. an accurate setting formula for interior angle of the microprocessor - based directional power relay as the protection in phase to phase short - circuit fault is proposed and analyzed, users can set as a calculation value or at least an optimum in the formula. therefore the operation sensitivity and reliability of the directional relay would be improved greatly. the opinion is new and practical

    文摘:保護相間短路的模擬式功率方向繼電器內角的整定值只有兩個（ 30 、 45 ） ，用戶只能在這兩個值中選其一；分析並提出了保護相間短路的微機型功率方向繼電器內角的準確整定計算公式，用戶可以整定為該公式的計算值或至少為最合理的值，從而能顯著提高方向繼電器的動作靈敏度及可靠性，具有新見解及應用價值。
