Substation safety equipment for power transmission and distribution

The five safety rules: 1. disconnect 2. secure against reconnection 3. establish absence of voltage 4. ground and short-circuit 5. cover or isolate adjacent live parts.
The safe use of voltage testers, earthing cables, earthing and short-circuiting cables, short-circuiting cables with rod earthing, earthing cables, operating cables, discharging devices, short-circuiting sets in switchgear, switchgear in the railroad sector, overhead lines, railroad power lines, railroad power lines enables professional voltage testing as well as earthing and short-circuiting. When using the earthing and short-circuiting cable, please note: The cable must be checked for condition by inspection before use. The cables may only be used in systems for which they are designed for short-circuiting currents. The cross-section information on the short-circuiting and grounding cables on each short-circuiting rail is decisive for this. Devices that are stressed once with the full short circuit. The life insurance of employees: when working on electrical equipment corresponds to grounding and short-circuiting. With the earthing and short-circuiting cable you ensure the voltage-free condition of the installation for the duration of the work. Regular inspection of the earthing and short-circuiting cable is required. Earthing and short-circuiting cable according to DIN EN 61230 (VDE 0683-100): 2009-07 are safety devices and are subject to the requirements of periodic inspection. Untested, defective earthing and short-circuiting cable are a high safety risk from the experience of the employers liability insurance association. To ensure safety when working on electrical equipment, tests are required in accordance with DGUV Regulation 3, §5 and DIN VDE 0105-100 (VDE 0105-100): 2009-10. Cable must be inspected before each use and at regular intervals. Visual inspection by the user himself is required. The ohmic resistance of the is measured statically and dynamically: single and multi-pole earthing and short-circuiting cables are measured through in terms of resistance and evaluated. Low-resistance measurement is performed both statically and dynamically. Dynamic means that during the measurement process the test object is moved and the cable is bent and pulled. The actual measured values are compared with the experimentally determined limit values. In this way, the condition of the line can be assessed and documented by comparison. The test is thus performed in three steps: 1. visual inspection 2. static test 3. dynamic test. Visual inspections without technical aids are subjective.

The earth rod bridges the distance between phase and earth and is at least as long as the insulator on the line support or device. The max. length of the rod earth electrodes is matched to the usual insulators. Higher voltages and thus longer rod earth electrodes cannot be realised due to the untested mechanical loads. Required information for the project planning of the rod earth electrode length as well as the selection and design of the required additional components. Range of application: Cable heights from approx. 8 metres to approx. 12 metres. Only vertical mounting possible, usually on cable supports, rarely on devices such as earth electrodes, disconnectors, transformers or others. Restriction: Stationary rod earth electrodes only move along a vertical line foot support, earthing and conductor fixed point must be on this line. Stationary rod earth electrodes are therefore only mounted where there can be no displacement between these important components (e.g. due to movement of the conductor). Required specifications: Conductor height (horizontal course), conductor material (Al or Cu), conductor type (tube, rope, single, double or multiple conductors), conductor dimensions (diameter, cross-section, distances in the case of double or multiple conductors), height of the earthed substructure, construction of the substructure (steel construction drawing, photos), details of the foundation if dimensions if the foundation impairs the functional space due to its extension. Details of any existing obstacles in or near the intended functional space Conceivable obstacles are e.g. corona rings, drives, cabinets for control, measurement and regulation technology or also neighbouring buildings, fences etc. a The specifications for the transportable rod earth electrode are more extensive in some points, because the system can be used in a more versatile way than the stationary rod earth electrode. In the following, reference is made to the additionally required specifications, conductor height (also vertical or oblique course), details of the device (drawing, photos), details (e.g. drilling patterns) of certain device components, if a fixed point is to be attached directly to the device. The project planning is successful if the location of the rod earth electrode is completely and correctly described by photos, drawings and dimensions.
