Abstract

The policy decisions made by BT in 1984, that the racked mounted power plant (RMPP) could be the method of providing DC power for all digital exchanges, proved to be correct. All equipment provision is now planned and installed with RMPP. The decision in 1989 to develop a centralized power plant (CPP) utilizing the same technology as RMPP was made out of the necessity to meet an increasing demand for a CPP that met the now more specialized needs of the power planners and maintainers. It too has proven to be correct. The number of CPPs in service in 1990 is shown. To meet the requirement for a modern CPP, a power system was developed that is suitable for installation in telecommunication equipment areas. It is modular in concept, using switched mode power supplies (SMPS), Rectifier 160 (R160), as the AC to DC conversion stage and sealed lead-acid cells for the short-term standby. The SMPS system is described
