零线

This conclusion is incomplete. We should consider the harm of faulted neutral line caused by unbalanced load.

必须考虑到三相不平衡负载状态下的零线断路同样可以造成这种危害。

The all-purpose safety plug has the advantages that when the contact of the earth wire is not conducted, the live wire and the null line can not be connected, in order to cut the power supply, therefore, the use safety is guaranteed.

优点：在地线触点未导通时，相、零线不能合上而切断供电，保障使用安全。

Commercial power input null line.

市电输入零线。

One of factors which activize the explosive development of cyclone exists strong convective instability in lower layers from the analysis of the barotropic potential vorticity.

气旋发展后期气旋中心上空300hPa以上位于位涡平流零线附近。850hPa以下的斜压位涡的正负值的变化与气旋的发展有很好的对应关系。

When the Oscillator is well above the zero line the market is said to be overbought.

当振荡器以及零线以上的市场被认为是超买。

Fix meter and calibration tooling board to 34 racks test bench together, loose the lower row screw, fix the upper row screw upper. Insert 4 pieces of current binding post into terminal 1,2,3,4, embed tightly, ensure connection is well. Clamp voltage line to terminal 1, clamp neutral line to terminal 2, align optical port with pulse LED, start to calibrate.

电表连同校表工装板一起固定到34表位校表台上，表的下排螺钉打松，上排螺钉固定，4根电流接线柱插入端钮盒1、2、3、4端子内，卡紧，确保接触可靠；将电压火线夹端子1上，零线夹端子2上，光电头对准脉冲灯，开始校表。

Current waveforms of the system without and with the line trap ...

对比阻波器投入前后的电流波形，由1个峰值大且陡的尖脉冲变成了2个平缓的尖脉冲，且电流峰值、3次谐波分量、零线电流都减小，改善了设备运行的工况，保证了继电保护动作的正确性和供电系统的安全稳定运行。

of using visual and manual inspection, using a dedicated tool for testing circuit test socket on the firing line, zero line and the ground whether the location is satisfactory.

采用目测和手动的方法检查，并采用电路测试的专用工具检验插座上的火线、零线和地线位置是否符合要求。

LV winding: star with the neutral outside.

低压线圈：星形，零线在外

PE or PEN line should connect to upper pole of single phase 3 pole socket, 3 phase 4 pole socket and 3 phase 6 pole socket.

单相三孔、三相四孔及三相五孔插座的接地或接零线接在上孔。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
