Live working. Portable equipment for earthing or earthing and short-circuiting (IEC 61230:2008)

Alkalmazási terület

This International Standard is applicable to portable equipment, with or without matching connection points, for temporary earthing or earthing and short-circuiting of electrically isolated 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 earthing and short-circuiting device and insulating component. An example is given in Figure 1a and Figure 1b. 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 1c; – separate components, such as conductive extension (see Figure 1b) or clamp or cable with end fittings. The performance of equipment, devices and components covered by this standard is based on electro-dynamic and electro-thermal effects acting during short-circuit. The withstand capability of the devices and equipment is expressed by their rated values of current, time and peak factor. No rated voltage is given, but the geometrical dimensions of the equipment are also linked to the voltage of the installation. Examples of connection diagrams of earthing and short-circuiting devices are given in Figures 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 and according to local or national regulation, such as live working or dead working procedures.
