適用范圍：This International Standard is applicable to portable equipment, with or without matchingconnection points, for temporary earthing or earthing and short-circuiting of electricallyisolated or de-energized a.c. and d.c. installations, distribution and transmission networks,whether they are overhead or underground or of low or high voltage.NOTE Annex A provides guidance for application to railway systems.This standard covers equipment comprising an earthing or a short-circuiting or an earthingand short-circuiting device and insulating component. An example is given in Figure la andFigure lb.It also covers:- earthing or short-circuiting or earthing and short-circuiting devices intended to be installed with insulating means. An example of an earthing device is given in Figure lc;- separate components, such as conductive extension (see Figure lb) or clamp or cable with end fittings.The performance of equipment, devices and components covered by this standard is basedon electro-dynamic and electro-thermal effects acting during short-circuit. The withstandcapability of the devices and equipment is expressed by their rated values of current, timeand peak factor. No rated voltage is given, but the geometrical dimensions of the equipmentare also linked to the voltage of the installation.Examples of connection diagrams of earthing and short-circuiting devices are given inFigures 2 and 3. Associated usual lengths of cables are given in Table 1.Not covered in this standard are:- insulating means, such as insulating sticks, telescopic sticks, insulating handles, insulating gloves, aerial devices with insulating booms, insulating ropes to be used to install the earthing and short-circuiting device;- insulating components, except for basic safety requirements for the insulating element; NOTE Basic safety recommendations for earthing sticks are given in Annex B.- devices meant only for the draining of induced currents;- relevant working procedures for using portable equipment for earthing or earthing and short-circuiting.NOTE The equipment complying with this standard should be used according to safe working procedures andaccording to local or national regulation, such as live working or dead working procedures.
