Surge protection is widely recognised in power networks due to the threat of lightning strikes, both local and distant, network switching, impulses from load switching etc. The power network can be vulnerable to transients, surges and impulses from these causes and there are many solutions providing protection.
DEHN Germany was founded in 1910 initially concentrating on lightning protection and earthing. In 1954 Dehn introduced the world’s first surge arrester and has now been at the forefront of surge and lightning protection products for more than 70 years.
The standards tell us protecting an installation at various boundaries of the Lightning Protection Zones (LPZ) of the installation is the best practice to be observed. However, our protection measures do not stop at the power network. It is essential to also consider the information technology infrastructure as well. This can include data networks, process control, and monitoring systems.
DEHN Blitzductor arresters are pluggable and universal multipole DIN rail mounted lightning current and surge arresters for protecting measuring and control circuits, bus systems and telecommunication systems. Ensuring effective protection of sensitive equipment under lightning and overvoltage conditions, the Blitzductor range combines the high impulse current discharge capacity of a lightning arrester with the low voltage protection level of a surge arrester.
The Blitzductor range provides solutions for a wide variety of information technology applications. When selecting a surge arrester various parameters need to be considered:
- The protective requirements
- Discharge capacity
- Voltage protection level
- The system parameters
- System voltage
- Nominal current
- Transmission parameters
- Installation environment
- Design
- Connection conditions
- Approval requirements
The Blitzductor range includes a universal base design for the protection modules that allows no signal disconnection if the protection module is removed. This important feature means the process or transmission protocol being protected is not interrupted during maintenance or replacement of a module. There is also a module locking system to ensure safe operation, even in high vibration applications.
There is a Blitzductor solution to suit a wide variety of bus systems and data networks as well as popular measuring and control protocols.
