trip relay

But the connection of wind power makes the districts show a typical character of week feed system which forms a great test for system relay protection especially in high frequency protection of which one line can falsely trip two times.

但风电的接入使得该地区电网呈现出典型的弱馈系统特点，这使得系统继电保护面临很大的考验，尤其作为高频保护，现场曾发生过同一条线路两次误动的现象。

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。

Each should provide independent DC trip power for each relay.

为每个继电器提供独立的dc跳闸电源.

Several typical problems existing in site test of relay protection are pointed out, such as test with load, channel test of high frequency protection, remote trip function test of optical protection.

针对现场试验中带负荷检查存在的问题、高频保护中通道问题、光纤保护中远跳功能应注意的问题等，指出应特别关注的问题。

Upon exceeding the trip point, the sensor applies voltage to the coil of the latching relay.

当超过断路点时, 传感器将电压加在关闭继电器线圈上.
