Common use of Drastic Action Limit Clause in Contracts

Drastic Action Limit. Use equations (4) and (5) as above Winter (5 minutes) Where Ii = (0.75 x 1.23 Ir) = 0.9225 Ir ⎡ ⎛ 0.9225 I ⎞1.8 − 5 ⎤ ⎢120 − (105 − 40)⎜⎜ r ⎟ e 30 − 10⎥ ⎥ Is = Ir ⎢ ⎝ r ⎠ 1.8 − 5 ⎥ ⎢ (105 − 40)(1 − e ⎢⎣ 30 ) ⎥ ⎥⎦ = Ir ⎡120 − 47.58 −10 ⎤1.8 ⎢⎣ 9.98 ⎥⎦ = 2.77 Ir , so use 2.0 Ir Where Ii = (0.75 x 1.10 Ir) = 0.825 Ir ⎡⎢ ⎛ 0.825I −5 1.8 e 30 1 ⎤⎥1.8 ⎢120 − (105 − 40)⎜ r ⎟ ⎥ Is = Ir ⎢ ⎢ ⎢ ⎢⎣ ⎝ Ir ⎠ − 28⎥ ⎥⎦ 1 ⎡120 − 38.92 − 28⎤1.8 s r ⎢⎣ 9.98 ⎥⎦ = 2.53 Ir , so use 2.0 Ir
