Abstract:
1. A method of dynamically composing a desirable trip curve for an electrical protection device, comprising: monitoring one or more input values of a device to be protected; defining the desirable trip curve as a function of the one or more input values of the device; selecting at least one parameter of the desirable trip curve; defining the selected at least one parameter as a function of the one or more input values of the desirable trip curve; defining a minimum and a maximum value of the selected at least one parameter; configuring at least one electrical circuit representing at least one of a minimum boundary trip curve defined by the minimum value of the selected at least one parameter of the desirable trip curve or a maximum boundary trip curve defined by the maximum value of the selected at least one parameter of the desirable trip curve; and dynamically modulating the at least one electric circuit after the configuring by selectively connecting, for a determined duty cycle, the at least one electrical circuit to an input terminal of a switching device such that an output signal representing the desirable trip curve is provided at an output terminal of the switching device for the duration of the determined duty cycle, and disconnecting the at least one electrical circuit from the input terminal of the switching device after the duration of the determined duty cycle.
