Solution to the Restraint Gear Shapper Addendum Strength to the Profile Shafted Coefficient by Charting Method 用查表法求插齿刀齿顶强度对变位系数的限制
When internal fault occurs, the phase angle difference of two end currents is small and the restraint coefficient is small, so the sensitiveness of relay is high. 内部故障时两侧电流相位差小, 则制动系数小, 保护灵敏度高。
