Abstract: A protective relay that derives and processes power system data from multiple user-configurable data source points. Data from multiple source points can be combined in the relay as a single source of data useful to perform a wide variety of monitoring and protection tasks. Multiple digital signal processing modules can be used to provide additional processing resources, including the ability to provide protection and revenue-class metering in a single device.

Abstract: A system and method for monitoring a utility substation is provided. The system for monitoring a utility substation includes monitoring equipment connected to a utility substation for monitoring operating conditions of the utility substation. The monitoring equipment is connected to an application service provider through a first communication network. One or more network interface devices are connected to the application service provider by a second communication network, which may be the same communication network as the first communication network. The one or more network interface devices receive notification of operating conditions of the utility substation monitored by the monitoring equipment through the application service provider.
