Figure 453: Operate time curve based on IDMT characteristic with Minimum
operate time set to 1 second
11.3.1.1 Standard inverse-time characteristics for overvoltage protection
The operate times for the standard overvoltage IDMT curves are defined with the
coefficients A, B, C, D and E.
The inverse operate time can be calculated with the formula:
