Panel - Reliability Tab

Click Import to import reliability data from the selected library, class, and category into the reliability data fields. After you import, the imported values appear below the Import button.

• Library: The reliability data library. We provide Annex Q data, but you can select your own library if one is available. Use the library to import reliability data.
• Category: The category for the component in the library data. For example, the category for a bus could be a control panel or a switchgear. The category determines which classes are available.
• Class: The class for the component in the library data. This is used to provide more exact reliability data based on the particular characteristics of the component.

Note: You can also import reliability data for all components in the one-line at the same time. See Importing Reliability Data for more information.

The calculated rate of failure for the component on a yearly basis. If you have imported library data, the imported value is displayed here. You can manually type a value to have the program use that value instead.

Note: For cables, transmission lines, and busway, this value is per unit of length.

The mean average time to repair the component, expressed in hours. If you have imported library data, the imported value is displayed here. You can manually type a value to have the program use that value instead.

Note: For cables, transmission lines, and busway, this value is per unit of length.

The mean average time to replace the component, expressed in hours. If you have imported library data, the imported value is displayed here. You can manually type a value to have the program use that value instead.

Note: For cables, transmission lines, and busway, this value is per unit of length.

The estimated cost to repair the component. This value is not used if the Action upon failure is set to Replace.

The estimated cost to replace the component. This value is not used if the Action upon failure is set to Repair.

The recommended action to take upon failure of the component: repair, or replace.

The downtime cost for the individual piece of equipment. This is available for a bus, MCC, panel, motor, or load.

This is an adjustable percentage that is applied to the failure rate of indirect protective devices and represents the percentage of total failures in each failure mode. For circuit breakers, the default is 9%. For switches, the default is 0% (no reliability).
