General Breaker Questions Dead Tank I’ve put a ...cimug.ucaiug.org/Focus_Comms/AssetHealth/Public Documents/Modeli… · On the 1st SF6 Dead Tank I’ve put a GeneralAsset instance

General Breaker Questions1. Heaters. On the 1st SF6 Dead Tank I’ve put a GeneralAsset instance with .kind=.breakerHeater attached to the mechansim. On the 2nd SF6 Dead Tank I have put a Asset instance w/ .kind=breakerHeater attached to each SF6 Dead Tank tank. Need to talk about which approach makes more sense and identify exactly those components we should hang heater instances off of. 2. CTs. What about modeling CTs as GeneralAssets now and save CTInfo until later… or maybe put just a .ratio attribute in CTInfo? (Would have one instance GeneralAsset w/ .kind= CT of every ratio for every model) Need to have a discussion about what different kinds of CTs are worth modeling.3. Do we need to model compressors on breakers? (Paul B says TVA tracks them)4. Interrupters appear not to have nameplates and make up an integral part of a breaker’s design, so they probably don’t merit creation of an InterrupterUnitInfo class. Are there, however, interrupter characteristics that merit attributes in SwitchInfo, perhaps (since all interrupters on a breaker would be the same)? Like type:· arc-assist (or arc-assisted)· self-blast (same thing as self-pressuring?)· puffer (double-nozzle quenching is variant, right?)· self-compression (2 moving contacts)· rotating arc· double pressureOr material:· porcelain· composite· silicon rubber· Brown/Grey· fiberglass

Note on use of AssetPosition:The AssetPosition class is intended to support utility-specific standardized definition of relative positions of similar asset components within an asset (or positions of assets among collections of assets).

In the asset health domain, two main drivers for defining position exist: - for unambiguous identification of a specific asset component (among many like components) by humans - for unambiguous identification of a specific asset component (among many like components) by systems that are not asset component “MRID” aware

In the CIM standard asset templates, where an association between an asset component and an AssetPosition instance is shown, the association from the asset component to some AssetPosition instance is required, though it need not be to an AssetPosition instance with the .position value shown in the template. Utilities are free to utilize their own position numbering conventions and to associate asset components to appropriate AssetPosition instances. The fundamental assumption is simply that when there are multiple similar asset components within an asset, each asset component will be associated with a unique AssetPosition instance to enable unambiguous identification.

In addition to the required AssetPosition instance associations, any Asset or Asset child instance can have an AssetPosition instance associated with it.

3 Break

Carey:I found product references to early SF6 dead tank 500kV breakers with 3 breaks. In an older textbook there was mention of “three or four (or more) series breaks”. Does AEP have some older 765 kV SF6 dead tanks? I’m thinking saying “n” make sense here.

SF6 Live Tank Examples (of types different from sample templates)


SF6 Live Tank Breaker· 36 kV – 800 kV· Insulator stacks provide electrical

isolation, SF6 provides arc-extinguishment

· 1 or 2 SF6-filled interrupter chamber(s) in top insulator(s) of insulator column, where one to four insulator columns can be used per pole, with interrupters in series.

SF6 Live Tank Questions1. Are there heaters on SF6 live tank breakers? Should they be modeled off each interrupterUnit if they exist?2. Does it makes sense to model Medium on these breakers? Some of what I’ve read indicates that some models are essentially sealed at manufacture. If we use Medium, does it associate with the InterrupterUnit or the insulating stack assembly? <there is perhaps a larger discussion about when modeling of Medium should be done… when it’s makeup or condition is a factor in health, when it can be replaced.. what else?>3. Is breakerInsulatingStackAssembly or insulatingColumnAssembly a better .type? (same question for air blast circuit breaker and minimum oil)4.There are never more than 2 breaks on an insulating stack, right?5. There is no reason (or place) to model a relationship on SF6 live tank breakers that reflects the moving / fixed contact, right?6. What is the maximum number of insulating stacks?
