Claim 0:
1. A method for remote activation of a communication module of a self-powered intelligent electronic device (IED) controlling an auto recloser, wherein the auto recloser and the TED are mounted on an electric pole of a power distribution network, wherein the TED is electrically coupled to a power line with a current transformer to measure a current flowing in the power line and provide a trip signal to interrupt the current in the power line, and wherein the TED is self-powered from power extracted from the current transformer, the method comprising, using a controller of the TED:
receiving an activation signal from a trigger source through an optical sensor to activate the communication module, wherein the trigger source is positioned within a predefined distance from the TED;
generating a control signal for powering the communication module from a power supply module based on the activation signal, wherein the control signal is generated upon the controller of the IED detecting the activation signal;
enabling the power supply module for powering the communication module for a duration controlled with the control signal; and
activating the communication module for communicating a plurality of data associated with the TED to a remote communication device upon enabling the power supply module for the communication module.
