Innovation and on-goingresearchThe PASS M00 module is the latest arrival in the PASS family.

PASS M00 is the tangible result of the experience acquired byABB in the field of multifunctional modules for High Voltagesubstations.

PASS M00 also represents the cutting edge when it comes tothe technological innovation achieved by ABB withmultifunctional modules for High Voltage applications. And thisis especially true of multifunctional units with unique innovativefeatures used in conjunction with components andtechnologies of tried and tested reliability.

The functional specificationsPASS M00 combines all the typical functions of a complete AIS bay forelectrical substations with voltage ratings up to 100 kV in a unit whosevolume is comparable to that of a conventional circuit-breaker of equal class.

It uses and widens the scope of the operating philosophy of the PASS serieswhose dominating factors, those that have definitely established theproduct’s success with over 800 risers sold throughout the world in just threeyears, are briefly outlined below:

• all the functions of a bay are combined in a single module

• the operating and interrupting functions are integrated within a housing inSF6

• the product is fully transportable and easy to install

• utmost reliability guaranteed by GIS technology

• extremely versatile when substation layouts/planning solutions are drafted

In the version for electrical substations with asingle bus-bar, PASS M00’s line diagram

layout corresponds to the drawing in the picture,which shows:

• the synchronous bus-bar; line disconnector• the circuit-breaker;• the current transformer;

The single- line diagram shows how PASS M00differs from the series in the higher class (PASSM0) as disconnection can be achieved on bothsides of the circuit-breaker. This occurs in thesynchronous mode thanks to the way the mobilecontacts rotate by means of a single drive.

Versatile operation

The single line diagram

Similarly to the higher class PASS series, PASS M00 features versatileoperation that knows no rivals in the field of High Voltage components. PASSM00 offers series of modules for HV substations featuring a single bus-bar,plus another series with a double bus-bar.

Here again, PASS M00 can be used as a multifunctional module forsubstation layouts such as the “incoming and outcoming” one with a singleHV component.

Moreover, PASS M00 can be supplied with a cable bushing of the GIS type.

In view of its low weight, PASS M00 can be used for “wall mounted”applications. This means that segregated High Voltage cells occupying more or less the same space as a medium voltage cell in air of the

old type can now be obtained. Thisapplication is undoubtedly the idealway to solve the problem ofupgrading in many industrialinstallations that currently operatewith Medium Voltage.

Last but not least, PASS M00 canalso be used as a HV bay on amobile truck, available inemergencies or if work must becarried out on already installed HVbays.

This latter application naturallyextends to integration of the PASSM00 module into the powertransformer to form mobilesubstations with up to 100 kV powerratings in a single trailer.

Impact on the environmentPASS M00 is environment-friendly. It has been designed incompliance with the philosophy of the PASS project, whichcombines functional and reliable systems with use of highlyrecyclable, non-energy consuming materials with a lowimpact on the environment.

Where materials with different characteristics had to beused, the greatest care was taken to obtain goodperformances while limiting the impact on the environmentas compared to that exercised by similar conventionalcomponents.

Typical examples are compositeinsulators. Since they are muchsmaller and lighter, and providehigher performances thanporcelain insulators, they lead toa drastic reduction in the use ofthe other materials that make upHV electrical substations, such asfoundation materials and thebearing structures of the module.

The fact that several functions areintegrated together also achievesan equally evident, drastic andglobal reduction in the impact on

the environment. This is because all the materials thatcontribute towards forming the typical conventional bay(such as the steel used to make the supports, the porcelainof the insulators, the concrete of the foundations, copper ofthe conductors and the aluminium used to connect thecomponents together, etc.) are completely eliminated.

Since the module is extremely small in size, it can also beused to build installations where the live parts andextremities of the system are further away from each other.This minimises the effect of the electromagnetic fieldsbeyond the actual installation itself.

Life Cycle CostThe CEI 56-13 Standards that stem fromStandard IEC300-3 act as guidelines whencalculating the Life Cycle Cost (LCC) of a product(an example is shown in the figure).Since 1999, ABB has also been using acalculation method that allows the cost of theentire life cycle of an installation (Initial Cost ofthe investment, Fixed Charges for managementand preventive maintenance, Variable Costs dueto corrective maintenance following faults) to beevaluated with mathematical methods, and tothus plan its innovative products with a view toreducing the global life cycle cost of theinstallation.PASS M00 is therefore the ultimate answer to thisapproach in technological terms. It is mainlydedicated to Managers, or people who mustcompare performances and relative coststhroughout the entire life cycle of the actualproduct, and not the mere technical aspects:products are no longer considered as atechnological end to themselves, but becomepart of the operating context of a process, towhose profitability they are strongly linked.As an example, just think of a conventional bayinstalled in an HV/MV substation in an operatingcement works: the cost for lack of productionwhen the system is out of service would be about3 times higher than the cost of installing PASSM00.Similarly, PASS M00 is more reliable since it isless liable to become faulty. Moreover, it needsservicing less frequently throughout the life of theinstallation and maintenance work can be carriedout much faster. If these features are consideredin relation to the process on the load side of theinstallation, it will be evident that PASS M00 isable to achieve remarkably interesting financialsavings.

PASS M00 uses a self-blast type circuit-breaker. The energy to operate on CB isprovided by a three-pole spring mechanism (BLK82) already used forconventional circuit-breakers of the same and superior classes like PASS M0 andCOMPASS with single-pole drive.

All this ensures highly reliable operation, as testified by the thousands of controlsof the same type installed in ABB’s circuit-breakers throughout the world.

Combined disconnectorCombined disconnectorCombined disconnectorCombined disconnectorCombined disconnector

PASS M00 extends the disconnecting concept using the same single drive as in PASS M0 series andallows the user to double disconnect the circuit-breaker on both sides by means of a singlesynchronous operation.

This is the innovation provided by PASS M00 and it has been achieved by partially turning the arcingchamber within the tank. The technology is the same as that used for larger, GIS bays. It thereforerepresents an absolute innovation, but one achieved through on-going experience.

PASS M00 takes advantage of the same concept for systems with double bus-bars, where thedisconnecting function covers the two bus-bars and the incoming feeder/transformer.

The synchronous disconnector also ensures that the feeder is earthed through the circuit-breaker or, ifrequired, the bus-bar, by turning the mobile contacts to a further extent.

Note how all the manoeuvres described above take place in SF6 atmosphere. This provides furtherguarantees as to reliability and fade-free withstanding properties regardless of the conditions outside.The disconnector’s position can be seen through the window at the bottom of the tank.

Here again, the current transformer makes use of PASS technology and is the“ring” type. Several cores can be installed, to suit the end customers’specifications. The transformer is generally fitted to the front bushing, but canalso be installed on the rear one to comply with specific requirements.

Quality CertificationPASS M00 is manufactured in compliance with thedictates established by the current ISO 9001 andISO 14001 standards.

The parts that are not produced by ABB itself aresubjected to strict inspections on arrival while therelative suppliers are chosen from amongstenterprises that comply with the current qualitystandards applied to products.

PASS M00 is completely assembled and tested inthe factory in compliance with the followinginternational Standards:• IEC Standards pertaining to the components

involved• ISO 9001 and 14001• CENELEC EN 50052• IEC61462.

Certificates attesting to the type tests conductedare available on request.

Composite bushingsComposite bushingsComposite bushingsComposite bushingsComposite bushings

The success of the PASS M0 series has also been due to use of compositeinsulator bushings which, as compared to the porcelain ones, provideabsolutely unrivalled performances, particularly in strongly pollutingenvironments. Just think of the hydrophobic characteristic of silicone, thematerial used to make the sheds, characteristic that is continuouslyregenerated as polluting substances settle.

It is also worthwhile remembering that these insulators are safer (explosionproof) and less fragile, an essential feature if the problems caused bytransport are to be avoided.

PASS M00 technology includes use of a smallquantity of SF6 to obtain the insulating andbreaking parameters required to operate themodule.

Each pole features a bursting disk with aparticularly precise activation threshold. Thisprevents over-pressures of the pulsing type fromreaching values that could jeopardise theinstallation and surrounding environment, thusguaranteeing the utmost safety during operation.

Along with the gas monitoring system, the productis fitted with a pressure gauge-densimeter tomeasure and monitor the density of the gas in thetank.

Technical specificationsInstallation methodThe installation sequence illustrated in the photos on this pageshow how versatile PASS M00 is and how easily it can behandled.

The module reaches the building site in a standard vehicle, towhich the local control panel and power module are fixed.

1. The module reaches the building site in a standard vehicle,in two parts: the main stand, to which the local control panelis fixed, and the power module.

2. The stand is unloaded and installed on site by means ofchemical anchors or rods. After this, the module is unloadedfrom the vehicle and positioned on the stand by the craneattachment on the vehicle itself.

3. The module can now be fixed in place and the panel’s powerconductors and auxiliary equipment connected.

4. Once the conductors and auxiliary equipment have beenconnected, the module is ready for functional tests. It canthen be powered and operated.

The entire installation can be completed in less than half a day.There’s no need to make comparisons with the time it takes toinstall a conventional bay: PASS M00 is certainly the winningtechnology.

ConclusionsThe advantages of PASS M00 are briefly outlined below:

• use of standard components for applications of the GIS type

• operating functions insulated in SF6

• small size and highly versatile use

• quick to install and minimum maintenance required

• highly compatible with the environment as compared toconventional solutions

• lower life cycle cost than conventional installations. (1) Consult Technical Specification UA600870 for further information(2) Single bus-bar.(3) Double bus-bar.
