setting is inversely proportional to L.le square of the
voltage . Alternatively the Hile megawatt loading could have
increased slightly above 361 megawatts due to a change in
system loading or a change in tap position of the phase
shifting transformer at Saunrl~rs, St. La"rertce. Shortly
before circuit Q29BD tripped, a tap setting change had
been made in such a direction as to increase the power
flow. In any event the pickup setting of the line backup
relay was reached and the circuit opened at the Heck end.
The opening of circuit Q29BD res~lted in the sequential
tripping of circuits Q238W, Q258W, Q24BD, and Q30AW. After
the opening h_' the first two circuit>;, determined by an
cveilt recol'Jer at Beck, the osdl1ograph at Beck started and
cs tab lished the sequential openings of cireui ts Q2SBW,
Q24BD, anJ Q30AW.
The opening of the five Beck 23U-kv. circuits occurred
over a period of 2.7 seconds, during which the initial flow
of sao megawatts fro~ the western New York area toward Beck
rp.versed and reached all estimated value of about 1,200 mega-
''''atts into western New York for a total cllange of 1,700
megawatts. This surge of excess power continued eastward
and southward from ~iagara, and back into Canada ov~r the
230-kv. tic line at St. Lawrence. Tili s 1inc was opened by
