To be able to use electrical energy in households, it must be transformed down from medium to low voltage must be transformed into low voltage in centrally located transformer stations, before it is distributed to the loads. In this context, it must be observed that voltages up to 1,000 V are termed low voltage. To prevent interruption and failure of the electrical energy supply, maintenance and repair work must be performed on the installation. To prevent accidents, tested high-quality products are indispensable. DEHN is your reliable partner.
Working according to the five safety rules
According to the Federal Statistic Office, approximately 50 fatal electric accidents have been registered in Germany since 2011. To minimise this number, it is mandatory to observe the five safety rules according to EN 50110-1 when working on electrical installations:
- Disconnect completely
- Secure against re-connection
- Verify that the installation is dead
- Carry out earthing and short-circuiting
- Provide protection against adjacent live parts
The wide use of electrical energy in all areas of life leads to higher requirements on the safety and reliability of power supply systems. Therefore, companies are trying to prevent interruption and failure of the electrical energy supply. To this end, maintenance and repair work must be performed in the electrical installations and networks. Since these installations and networks frequently cannot be disconnected for technical and organisational reasons, work must be performed under live conditions. This work may include live cleaning, but also disconnection, protection against re-connection and verifying that the installation is dead. To prevent accidents, tested high-quality products are indispensable. DEHN is your reliable partner.
