三绕组变压器的基本百分比差动操作原理由以下方程说明：（EQ 5.4）两绕组变压器的基础百分比差动操作原则由以下方程解释：（EQ5.5）其中I restraint=相位、比率和零序校正后电流的每相大值；I differential=相位、比率和零序校正后的每相矢量电流之和注：在上述方程中，考虑了由于接线而产生的180°相移，因此使用+号来获得差分电流。差分设定点百分比的基础是S2系统设置 绕组1 绕组1相位CT主设定点值。差分设定点百分比如下所述。•百分比差动拾取：输入操作所需的小差动电流。此设置是根据正常工作条件下可能出现的差动电流量选择的。•百分比差动斜率1：输入双斜率百分比差动元件的斜率1百分比（差动电流与限制电流的百分比）。斜率1设置适用于零到拐点的约束电流，并定义了差动电流与约束电流的比率，超过该比率，元件将运行
The basic percent differential operating principle for three-winding transformers is illustrated by the following equations: (EQ 5.4) The basic percent differential operating principle for two-winding transformers is illustrated by the following equations: (EQ 5.5) where I restraint = per-phase maximum of the currents after phase, ratio, and zerosequence correction; I differential = per-phase vector sum of currents after phase, ratio, and zerosequence correction Note In the above equations, the 180° phase shift due to the wiring connections is taken into account, hence the + sign to obtain the differential current.The base for the percent differential setpoints is the S2 SYSTEM SETUP  WINDING 1  WINDING 1 PHASE CT PRIMARY setpoint value. The percent differential setpoints are explained below. • PERCENT DIFFERENTIAL PICKUP: Enter the minimum differential current required for operation. This setting is chosen based on the amount of differential current that might be seen under normal operating conditions. • PERCENT DIFFERENTIAL SLOPE 1: Enter the slope 1 percentage (of differential current to restraint current) for the dual-slope percent differential element. The slope 1 setting is applicable for restraint currents of zero to the kneepoint, and defines the ratio of differential to restraint current above which the element will operate
