Table 12 - Branch Data ID# = Branch identifier. Inter area branches are indicated by double letter ID. Circuits on a common tower have hyphenated ID#. Lam-p = Permanent Outage Rate (outages/year). Dur = Permanent Outage Duration (Hours). Lam-t = Transient Outage Rate (outages/year). Con = Continuous rating. LTE = Long-time emergency rating (24 hour). STE = Short-time emergency rating (15 minute). Tr = Transformer off-nominal ratio. Transformer branches are indicated by Tr <> 0. ID From To L - Perm. Tran.

have common Right-Of-Way (ROW) or Common Structure (CS) are indicated by loops lettered A - G in the one-line diagrams, the common lengths (miles) are as follows: A - 45 (ROW), B - 15 (CS), C - 18 (CS), D - 34 (ROW), E - 33 (CS), F - 43 (CS), G - 19 (CS). It is recommended that common mode outages on CS circuits be assigned a frequency of 7.5% of the outage rates presented in table 12; this should be applied for both permanent and transient common mode outages. The time taken to restore one circuit is the same as the permanent outage duration given in table 12, while the second circuit will take as long again.
