Information
This formula determines the interval for testing a protective system with an m-out-of-n voting logic, where n is the total number of parallel protective devices, and m is the number needed to activate the protection. The formula uses 'r', which is calculated as: r = n - m + 1. For example, in a 2-out-of-3 voting system, n = 3, m = 2, and r = 2.
Input Parameters
Enter the system parameters to calculate the Risk Based Voting Failure Finding Interval (FFI).
