Reliable power generation for telecommunications
November 2015

“Telecommunications plays an increasingly vital part in all aspects of commerce – particularly in data processing centres and base transceiver stations (BTS) – and is absolutely dependent on a reliable power supply,” says Grant Robertson, managing director, Vert Energy. “In the event of a power outage, backup generator units are used to ensure continuous and efficient operation of the network and can maintain power for several days.
“Low voltage generators, fitted with alternators from the Leroy Somer Partner range, offer reliable solutions that are specially adapted to backup BTS sites in the telecoms industry. These robust alternators ensure an uninterrupted power supply for the continuous reception and transmission of data, power to the computer and storage systems, and power for the building’s lighting, air conditioning and safety systems.”
Vert Energy supplies Leroy Somer Partner alternators, from 250 to 3250 kVA, specially designed to meet the demands of data centres. These energy efficient alternators have low reactance and improved performance with reactive loads. They have a greater starting capacity and are capable of supporting high load variations. The company also has specific winding designs to reduce harmonic distortion, depending on which harmonic needs to be suppressed.
Base transceiver stations, with relay emitters, also require a continuous power supply to facilitate dependable radio access for cellphones in their coverage area. Vert Energy’s solutions for BTS relays include alternators, from 8,5 to 80 kVA. The company also offers a variable DC generator designed especially for this application. The variable speed option optimises fuel consumption as the engine speed is reduced according to the load requirements. An additional benefit is the need for fewer components used in the rectification from AC to DC as used in a traditional power generation system.
