IEEE C37.112-2018 Inverse-Time Equations: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ t = TD × (A / (M^p - 1) + B) Where: t = Operating time (seconds) TD = Time dial setting M = Multiple of pickup (I/Ipickup) A, B, p = Curve constants IEEE Curve Constants: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Moderately Inverse (MI): A=0.0515, B=0.114, p=0.02 Very Inverse (VI): A=19.61, B=0.491, p=2.0 Extremely Inverse (EI): A=28.2, B=0.1217, p=2.0 Short-Time Inverse (SI): A=0.00262, B=0.00342,p=0.02 Long-Time Inverse (LTI): A=5.95, B=0.180, p=2.0 Long-Time EI (LTEI): A=5.67, B=0.352, p=2.0 IEC 60255 Curve Constants: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Standard Inverse (A): A=0.14, B=0, p=0.02 Very Inverse (B): A=13.5, B=0, p=1.0 Extremely Inverse (C): A=80, B=0, p=2.0
