1·The overload relay should not trip too soon on this condition.

在这种情况过载继电器不应过早动作。

2·When the relay operates, one or more contacts will operate and energize a trip coil in a Circuit Breaker and trip (open) the Circuit Breaker.

当继电器动作时，一个或多个接触器动作且给断路器的脱扣线圈通电，从而将断路器断开。

3·Reverse power relay trip test.

逆功率脱扣测验。

4·Reverse power relay trip test.

逆功率脱扣试验。

5·The protective relay is a sensing device, which senses the fault, determines its location and then send command to the proper circuit breaker by closing its trip coil.

保护继电器是一个传感装置，感官的过错，确定其位置，然后发送命令关闭其旅行线圈到正确的断路器。

6·For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.

对于后备保护装置防止高阻抗接地故障，将配置一只双极方向过电流继电器，同瞬时跳闸附件的时间成反比。

7·User is able to set the ground fault trip current of the relay just milliamps above the highest level, to accurately measure the system charging.

使用者可将继电器接地故障跳闸电流设置为高于最高值几毫安，以准确测量系统充电。

8·The distance protection with inverse time characteristic is the best choice to solve the conflict between fast trip near the protecting relay and reliable trip at the end of protection zone.

反时限距离保护是解决近范围快速动作与保护范围末端可靠动作之间矛盾的最好策略。

9·And also, trip and auto close operation of relay can be simulated.

同时还可以模拟保护对线路的跳闸、重合闸等操作。

10·Conventional impedance relay will refuse to trip according to an analysis of measuring impedance by means of impedance locus method when wrong-phase-coupling of traction power supply system occurs.

首先通过测量阻抗轨迹法对异相短路故障的测量阻抗的进行分析，得出牵引网发生异相高阻电弧短路故障时，常规原理的阻抗保护将拒动的结论。
