Power Stability for Telecoms project

7320 and 9130 used in remote locations

The power provision to telecoms transmitters in remote locations throughout Northern Africa has recently been improved with new emergency power installations. 

Grid failures are common place in many areas of Africa leading to regular disruption of vital services for telecoms providers.  In this recent project, each transmitter has been fitted with a standby generator set with an enhanced fuel capacity and the ability to start automatically in the event of a grid power failure. 

The generator sets are extremely compact, allowing extra space for the larger fuel tank. This allows the generators to run for longer periods of time, reducing disruptions and keeping telecoms services much more stable. 

Fitted with DSE7320 Auto Mains Failure control modules which constantly monitor the mains supply, the modules will, in the event of a failure, issue a start command to the generator which will be up and running within seconds and ready to take the load.  The DSE9130 Battery Charger is also used within the panel to ensure the battery is kept to its optimum level ready for starting the engine. Often the battery of a generating set is neglected as an important component of the application.  However, in such remote and critical applications, it is vital that the battery is reliably maintained.   The reliability and high number of protections offered by the DSE controller and DSE battery charger solution makes this a safe system that has led to a much more robust telecoms infrastructure. 

The DSE7320 modules offer sophisticated 3-phase monitoring of the power supplies (both mains and generator).  Secure remote access to the system is provided through the modules built-in RS232/485 ports, providing vital information and alarms on fuel level/usage, and system status offering huge cost saving benefits for maintaining these remote locations.  The modules will log 250 historical events and the configurable language display options allow for variations in regional language and dialect.
