Current value of the phase A on device's terminal. The source configured in the StudyInputSource property indicates for the Module the current system's load and the SelfHealing source indicates the current that passes through a device when the next opening or closing trigger is executed by the Self-Healing Module. The SelfHealing source indicates the modulus and the direction of the future current (a positive value means that current is an input to the Terminal in which this Measurement is instantiated and a negative value means that current is an output to the Terminal).
