PASS M0 - Innovative solutions for distribution substations up to

The conceptIn the today’s changing market, thesubstation is becoming more and more akey element to meet end users requirementssuccessfully and economically. Many existingsubstations have outlived their operational lifeand a one-to-one replacement of conventional AIScomponents like circuit-breakers anddisconnectors is not economically advisable;completely new substations have to meet toughrequirements in terms of occupied space,environment and availability. Substationsextensions require high flexibility on primaryequipment, to cope with already existing controlsystems, lack of available space, limited downtime.PASS M0 is the ideal primary equipment to meetall the above scenarios and it is the result of adifferent thinking; think for the performance of thesubstation as a complete system.PASS M0 switchgear limits the number ofequipment to what is really necessary to assurethe best functionality of the bay; its modular designassures all the possible substation layouts can berealized.BusBarFig. 1PASS M0 in its standard configuration (Single BusBar):1: Combined disconnector/earthing switch2: Circuit-breaker3: Current transformer.LineThe flexibilityPASS (Plug And Switch System) is based on ABBextensive experience in manufacturing bothairinsulated switchgear (AIS) and gas-insulatedswitchgear (GIS).PASS can also be thought as “Performance AndSave Space”: any substation layout can be metwhile making efficient use of available space.Performance is guaranteed by the wealth ofexperience in research and development,manufacture and operation of switchgear whichconstitute the basis of ABB know-how.The key characteristic of PASS is its compact andmodular design which encompasses severalfunctionsin one module, as for example:● Bushings for connection to one or two BusBarsystems● One circuit-breaker● One or more combined disconnector/earthingswitches● One current transformer2 - PASS M0
