Idmt function
Here, as defined in IEC 60255, the IDMT Tripping Time T(s) is multiplication of Time Setting Multiplier (TSM) by the k curve constant divided by the division of fault current I(F) in Amps to relay Current setting Is(A)in amps power of curve constant α minus 1. Hence the formula can be written as, T(s) = TSM * … Meer weergeven Also, the IEEE section C37.112-1996 defines the IDMT timing in seconds by the below formula, t(s) = TD/7 ((A / (I(F)/Is)p– 1) + B) Normal range of TD is 0.5 to 15 Hence, the … Meer weergeven According to American standard the over current relay is classified based on the following, 1. Definite minimum- CO-6. 2. Moderately inverse – CO-7 3. Inverse, CO-8. 4. Very inverse – CO-9 5.
