Abstract: The invention relates to remote activation of a communication module of a self-powered intelligent electronic device (IED). The IED controls an auto recloser mounted on an electric pole of a power distribution network. A controller of the IED, receives an activation signal from a trigger source, positioned within a predefined distance from the IED, through an optical sensor to activate the communication module. A control signal is generated, upon the controller of the IED detecting the activation signal, for powering the communication module from a power supply module. The power supply module is enabled to power the communication module for a duration controlled with the control signal. The communication module is activated for communicating a plurality of data associated with the IED to a remote communication device upon enabling the power supply module for the communication module.
