8 Busbar compartment The busbar compartment is located in the middle section of the switchgear. Main busbars can be located at the top, in the centre or at the bottom of the panel depending on the selected design and they distribute the power to the various switchgear panels. In some of the existing configurations main busbars can be directly connected to a circuitbreaker as well. Distribution busbars are located into the single column and positioned vertically to feed panel circuit-breakers. The busbar system can be composed by 1, 2 or 3 busbars per phase, according to requested rated current, short-circuit level and operational ambient conditions in terms of temperature, altitude and humidity. Busbars are normally bare copper made, on request can be suitably treated with tinning, silver-plating and/or sheathing. Main busbar system with connections for incoming busbars and bus-tie from the top Main busbars PC3.0/MNS R main busbars are available for currents up to 6300 A. Main busbars, as well as distribution busbars, can be completely segregated. Each PC3.0/MNS R panel can be fitted with three busbar systems at the same time (top-centre-bottom) each segregated from the others.

21 Versions Intelligent switchgear Thanks to the use of electronic releases with dialogue function, the air and moulded-case circuit-breakers mounted inside the switchgear can be controlled and managed by a supervision system. To integrate the moulded-case and air circuit-breakers fitted with electronic releases into correct installation management, ABB supplies SD-View 2000, a ready to use system consisting of software which, when installed on a personal computer with standard configuration, allows full control of the low voltage electrical installation. Modbus RTU, the recognised standard in the electrical distribution sector, is supplied as the communication protocol. Applications SD-View 2000 is a system specially studied for application in those electrical distribution installations which require efficient management without the need to use complex and costly systems. It is able to dialogue and control all the protection units of the installation and, in particular, low voltage Tmax, Isomax and Emax series of circuit-breakers in the following configurations: Tmax T4 and T5 series of moulded-case circuitbreakers fitted with PR222DS/PD release Isomax S from S4 to S7 series of moulded-case circuit-breakers fitted with PR212/P release and PR212/D-M communication unit Emax E1 to E6 air circuit-breakers fitted with PR112/PD or PR113/PD Modbus releases. Tmax T4 and T5 Isomax S4 S7 Emax E1 E6 20 ABB

22 SD-View 2000 is the ideal tool available to managers in order to have the situation of the plants under control at all times and to be able to control all their functions simply and immediately. The operator station (personal computer) allows information to be received from the installation and to control the circuit-breakers and relative releases. In particular it is possible to: send opening and closing commands to the circuit-breakers read the electrical values of the installation (current, voltage, power factor, etc.) read and modify the trip characteristics of the protection unit determine the status of the apparatus (open, closed, number of operations, trip for fault, etc.) determine abnormal operating situations (e.g. overload) and, in the case of releases tripping, the type of fault (short-circuit, ground fault, value of the interrupted currents, etc.) log the history of the installation (energy consumed, most highly loaded phase, any warnings of anomalies or faults, etc.) illustrate evolution of the installation over time by means of graphic diagrams. Access to the various functions of the system can be enabled by means of a password with different levels of authorisation. Putting the SD-View 2000 system into service is simple and rapid: in fact, the software itself guides the user in recognition and configuration of the protection unit. The user only needs to know the characteristics of the installation. Operator use is extremely simple: the graphic pages of SD- View 2000, based on Internet Explorer, make management of the installation as simple as surfing the Internet. The graphic pages relative to each circuit-breaker are particularly intuitive and easy to use.
