A monitoring system includes at least one monitoring devices coupled to electrical power distribution system at selected locations for collecting data related to the operation of the monitored system. The monitoring device(s) includes a communication port and processors programmed to segment the collected data into blocks optimized for user analysis operations, encrypt the segmented blocks of data, bundle the encrypted blocks of data with unencrypted metadata that identifies the data blocks by at least the monitoring location at which the encrypted blocks of data were obtained and the type of data, and transmit the encrypted blocks of data with the unencrypted metadata. The system includes at least one client device that has a communication port that is coupled to the monitoring device(s) and the client device and that has a processor programmed to generate and transmit queries regarding selected ones of the encrypted blocks of data.
