(sequence) Heading Description
plant - "U"; if a transmission line - "L"; etc. Conflicting
information will not be recognized and accepted by
the computer program, such as a type "T" or "L" for a
substation, "S" for a transmission line, etc.
Indicate nominal voltage of every facility (line,
substation, bus, etc.) in kV, with no more than one
figure to the right of the decimal point.
In the event operation of equipment results in a bus
outage at a station which contains two or more bus
sections at the same voltage, identify the particular
bus section(s) involved, such as "1 ," "A," "NW" for
Northwest, etc. Confine the designation to a maximum
of four characters. Otherwise, leave this column blank.
Indicate by "Y" for "yes" if equipment operation at a
switchyard or substation resulted in deenergization of
a bus section, even momentarily. For operation of
one or more switches or breakers which did not result
in an outage of a bus, indicate "N" for "no." Every entry
for an individual bus within a station, should include
either a "Y" or "N" in this column. This column should
be blank for all entries concerning transmission line
or transmission cable outages.
This column always should have all entry for each
facility outage reported. If the duration is 1 minute or
less, indicate "MOM" (momentary). If more than
1 minute, indicate the extent in hours and/or minutes,
with a colon separating hours and minutes. The duration
to be indicated for a variety of representative outage
conditions can best be described by reference to the
sample form PO&M-62,
some of the following instructions differ from those
contained in earlier issues of this document.
For a short-duration outage on a line with no
intermediate sections or other facilities between the
terminals, the duration to be reported, even if the
breaker(s) opened at only one end, would be "MOM"
(momentary) if 1 minute or less, such as the entry for
the 1st day of the month at 0029 hours. If the outage
was longer, the duration to be reported would be the
elapsed time that the line was not available for through
power transfer, such as the entry for the 27th day of
the month at 2207 hours.
