System Design for Stand-By Power Supply

Abstract

Telecommunications is playing an increasing important role as part of the infrastructure for sociel life. Therefore, when telecommunications service is interrupted, it causes serious disruption of social activities. Power systems are important for telecommunications service because they provide the lifeblood of the telecommunications network. Stand-by power, which is part of the telecommunications power system, backs up commercial power sources and improves the reliability of the power supply system. This paper discusses the concept of stand-by power supply, range of engine-generator applications, battery holding-time and the stationing standard for mobile and transportable generators. This paper also introduces stand-by power system for a digital network.
