full form of IDMT it’s inverse define minimum time
IDMT Curve formula they are
For normal inverse formula = TMS X 0.14 /Ir^0.02-1
For Very Inverse formula = TMS X 13.5/Ir-1
For extremely inverse formula = TMSX80/Ir^2-1
For Long Inverse formula = TMS X 120/Ir-1
On this formula TMS is time Multiple
Ir is fault current / normal current (or set current)
