Before the operation should first inspect the welding machine and the tool insulation, the welding machine outer covering protective earthing and the welding machine various wiring points and so on, the confirmation safe qualified only then work.[translate] ...
aBut no matter which grounding method be chosen, we should focus on limited single-phase earthing fault current, as far as possible to reduce its harmfulness. 但着陆方法被选择的不论,我们应该集中于有限的单阶段接地故障潮流,尽可能的减少它的有害。[translate] ...
Earthing isused to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the ...
TN-C–SEarthing the supply neutral at several points. The supply cables have a combined neutral and earth metallic outer sheath with a PVC covering (CNE cables). The combined neutral earth sheath is the PEN (protective earth neutral), conductor. The supply within the customer’s premises would...
second between the two poles, meaning that current can then flow. The arc burns between the workpiece and the electrode. This creates the required fusion heat. Via the consumable core wire and the coating, which is also consumable, the electrode also supplies the protective slag and the gas ...

Earthing is a common term used outside the US and is the connection of the equipment and facilities grounds to Mother Earth. This is a must in a lightning protection system since earth is one of the terminals in a lightning stroke. Bonding Bonding is the permanent joining of metallic parts...
