This paper examines the array of challenges currently faced by the telecom industry, including circuit to packet network migration, voice over IP (VoIP) telephony, and reliance on the Internet for worldwide commerce, that have led up to an increased reliance on high-quality extended backup power. It assesses traditional backup solutions in the context of the history of the telecom industry and compares...
In spite of a number of new, alternative power supply back up technologies, batteries are here to stay. Continuous monitoring of back up systems on the battery level becomes a vital factor of many mission-critical installations. In this paper, the authors explore the possibilities of implementation of new generation, state of the art battery monitoring systems based on wireless technology. This technology...
Charge balance is known to be an essential consideration in series valve-regulated lead-acid (VRLA) battery applications. Conventional applications use passive equalization to maintain balance: periodic overcharge sequences. Active equalization uses external circuits to enforce charge balance without the need for overcharge. There is little published data to show the potential value of active equalization...
In the highly competitive context of deregulated world energy, transmission utilities have a need for monitoring devices, using microprocessor based technology in order to optimize asset management within substations. A second-more sophisticated- generation of devices, adding protection and control to monitoring, is seen as the next step to decrease additionally the scheduled maintenance expenditures,...
