B) This section of the graph offers a truncated identifier for the porcelain testers being
scanned.
a. 0033 identifies the particular power transmission line being scanned
b. 1028 identifies a particular tower associated with the power transmission line
being scanned
c. U indicates the power phase associated with the power transmission line being
scanned
d. 01 indicates that it is the 1
st
