The power supply to telecommunications transmitters located in remote regions across North Africa has recently been improved with newly installed emergency power systems. In many parts of Africa, mains failures are common, which regularly leads to interruptions in vital services for telecommunications providers. In this latest project, each transmitter has been fitted with a standby generator set that has increased fuel capacity and can start automatically in the event of a mains power failure. The generator sets are extremely compact and provide additional space for a larger fuel tank. This allows the generators to run for longer, reduces interruptions and keeps telecommunications services far more stable.
In the system, which is fitted with DSE7320 Auto Mains Failure control modules that continuously monitor the mains supply, the modules issue a start command to the generator in the event of a fault; the generator starts running within seconds and is ready to take the load. The panel also uses a DSE9130 Battery Charger to keep the battery at the optimum level, ready to start the engine. As an important component of the application, the generator set battery is often overlooked. However, in such remote and critical applications, reliable maintenance of the battery is vital.
The reliability and numerous protection features offered by the DSE controller and DSE battery charger solution have made this system secure, enabling a far more robust telecommunications infrastructure. The DSE7320 modules provide advanced 3-phase monitoring of the power sources (both mains and generator). Secure remote access to the system is provided via the modules’ built-in RS232/485 ports; this access delivers vital information and alarms about fuel level/usage and system status, providing major cost savings for the maintenance of these remote locations. The modules record 250 historical events, and configurable language display options accommodate regional language and dialect differences.
