A system for locating a source in an electrical structure comprising: a plurality of drones capable of hovering in positions to form a virtual enclosure around an electrical structure, wherein the virtual enclosure is divided into a plurality of cells, each drone being configured to: measure a plurality of time difference of arrival (TDOA) values from signals originating from the source; calculate a plurality of propagation times comprising a propagation time for a calibration signal that travels from a respective drone to each of the plurality of cells; and send the plurality of TDOA values and the plurality of propagation times to a server; a server communicably coupled to the plurality of drones configured to: receive the plurality of TDOA values and the plurality of propagation times from the plurality of drones; and determine a location of the source based on the plurality of TDOA values and the plurality of propagation times.
