摘要
差动继电器按环流平衡原理工作,包含对流入、流出保护设备的电流进行幅值和相位的比较。在外部故障时,这个合成电流(乘平衡系数K1,K2)流过运行继电器(K.1I1-K.2I2)的值应为零。分析了平衡系数计算。
The differential relay operate in term of the circulating current principle. It involves a direct comparison of the magnitude and phase of the current entering and leaving the protected equipment,when external faults happened, the composed current (multiply balance coefficient K1,K2) through operating relay ( K1·I1-K2·I2) should be zero. This paper analysis the balance coefficient calculation
