1. A method comprising:
triggering, by a gateway device and at a first time, based on at least one of a first sampling frequency or a first data length of a first intelligent electronic device (IED), a capture of a first waveform from the first IED, the first IED associated with a first asset in a power system;
transmitting, by the gateway device, the first waveform to a remote device;
creating a first cluster of assets including the first asset and a second asset;
triggering, by the gateway device, based on at least one of a second sampling frequency or a second data length of a second IED, a capture of a second waveform from the second IED, the second IED associated with the second asset in the power system;
sending, by the gateway device and to the remote device, the second waveform;
establishing an operational baseline for the first cluster of assets based on the first waveform and the second waveform;
extracting fault features from the first waveform corresponding to different failure modes associated with the first asset of the power system;
determining, based on the features extracted from first waveform, that a fault of a first fault mode has occurred in the first asset; and
providing an alert that the fault has been identified, wherein the alert initiates or facilitates a control action in the power system.
