Integrated Building Services (IBS) can be defined generally as an array of facilities and services (sub-systems) which are provided for an office complex, a telecommunications centre, a data processing centre etc. and which are connected to, controlled, monitored and managed by a computerised system. In the last ten years, Telecom Australia has provided and installed several computer controlled building Automation systems for a number of large telecommunications centres in Australia. The systems are given the name of Local Monitoring and Control Systems (LMCS) and provide primary control and monitoring services in a localised area. The basic purpose of the LMCS is to monitor and control air conditioning systems, power supply and distribution including emergency generating systems, fire detection, security and other systems in the building complex. Telecom Australia has taken steps to meet the challenge of the new trend in this field and is particularly interested in the design of and innovation in intelligent buildings. A system specification to serve as functional briefing for building developers has been developed for use in deliberations on requirements for Telecom Australia's proposed corporate Head Office complex in Melbourne and other major office accommodation complexes.","PeriodicalId":129305,"journal":{"name":"INTELEC '87 - The Ninth International Telecommunications Energy Conference","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126114303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The design of the largest rectifier, HFC 48/200, a 200A unit, was presented on INTELEC -83 in Tokyo by Mr. I. Narvhus. This paper deals with the experiences gained from the development and operation of this unit. The HFC 48/200 has been in production since 1985. Approx. 120 units are in operation as per March-87, feeding ITT1240 digital exchanges in Norway. The largest plant installed consists of 18 rectifiers, i.e. 3600A. The main subjects discussed are as follows: Design and specifications. Experiences with the chosen design, presented at INTELEC-83, emphasizing the transistor chopper, internal noise problems and the control circuits for ripple regulation and parallel operation. The HFC 48/200 meets or exceeds all the Norwegian Telecommunications Administration (NTA)s requirements. EMC. General considerations about EMI problems in switch mode power supplies (SMPS). Mains and output EMI filtering of SMPSs feeding telecommunication equipment. Measurements of EMI on the HFC 48/200 and HFC 48/33. Operational experience. The designs chosen for the transistor chopper and base drive circuits have proven its reliability. Both experiences concerning harmonic distortion on the mains and parallel operation are discussed.","PeriodicalId":129305,"journal":{"name":"INTELEC '87 - The Ninth International Telecommunications Energy Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130109965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
