Radio base station - a.c. power supply
Protection of the radio base station
The radio base station is typically supplied by a separate line – irrespective of the rest of the building. The supply line to the cell site downstream of the meter and in the a.c. sub-distribution board upstream of the radio base station should be protected by adequate lightning current and surge arresters. This is required by the guidelines of all network operators, the German “ABB bulletin No. 16” as well as DIN VDE 0800-300 or IEC 62305.
Preventing false tripping of system fuses
The infrastructure in main and system power supplies is protected by proven combined arresters (combined lightning current and surge arresters). DEHN combined arresters are characterised by an extremely high follow current extinguishing and limitation capability, thus preventing false tripping of system fuses which would disconnect the cell sites. This leads to an extremely high system availability.
DEHNvap particularly for cell sites
DEHNvap CSP was specifically designed for the requirements in the mobile radio sector. This arrester can be universally used irrespective of the power system. Thanks to its integrated 3+1 circuit, it reliably protects TN-S and TT systems.
