Note 1 to entry: Then the derivative action time is given by *T*_{D} = *K*_{D}, where *K*_{D} is the derivative action coefficient.

Note 2 to entry: The derivative action time can also be given as the duration of the time interval required by a rampwise variation of the input variable of a derivative element to reach the value of the stepwise variation of its output variable.

Note 3 to entry: This entry was numbered 351-28-26 in IEC 60050-351:2006.
