A switching device for controlling power flow on a power line. The device includes a current sensor for measuring primary current on the line, a first voltage sensor for measuring primary voltage on the line at one side of the switching device, and a second voltage sensor for measuring primary voltage on the line at another side of the switching device. An ADC converts measurement signals from the current sensor and the voltage sensors to digital signals, and a PMU calculates magnitude and phase angle synchrophasor data using the current and voltage measurement digital signals and calibration data.

Automated control of a power network is provided by: providing multiple intelligent power controllers (IPCs) associated with multiple components of the power network, each IPC being associated with a different component; obtaining at least one raw data stream representative of at least one operational aspect of at least one component of the multiple components; and automatically associating, by at least one intelligent power controller associated with at least one component, metadata with the at least one raw data stream to produce at least one self-identifying data stream. The associated metadata describes one or more characteristics of the at least one raw data stream, and the at least one self-identifying data stream facilitates automated creation of predictive process models to assist in automated control of the power network by an IPC manager of the power network.

A technique is provided for automatically controlling configuration of a power grid, which includes one or more stand-alone sub-grids. Each stand-alone sub-grid includes a power generator, and a load is associated with the stand-alone sub-grid(s). The technique includes: monitoring the power grid by monitoring power demand of a load associated with the stand-alone sub-grid(s) and the power generated by the power generator within each stand-alone sub-grid; automatically determining that a grid configuration change is required for the power grid based on the monitoring; and dynamically reconfiguring the power grid by automatically modifying a number of stand-alone sub-grids in the power grid without interrupting power to the load associated with the stand-alone sub-grid(s) of the power grid. In one implementation, the power grid is a mobile power grid, and the power generator of each stand-alone sub-grid is a portable power generator.

A chain pull analyzer system including a telemetry unit for sensing the strain experienced by the chain while under load and in operation and for transmitting a radio frequency signal proportional to the strain and a data unit for receiving the radio frequency signal transmitted by the telemetry unit and for producing strain data output based on the radio frequency signal. The telemetry unit includes a strain sensing unit for sensing the strain experienced by the chain while under load and in operation and for producing an electrical signal based on the strain, the strain sensing unit including a body member for replacing one of the center links of the chain; a signal conditioning unit for converting the electrical signal produced by the strain sensing unit to an analog signal, the signal conditioning unit including a body member for replacing one of the center links of the chain; a radio frequency transmitter unit for transmitting the analog signal of the signal conditioning unit, the radio frequency transmitter including a body member for replacing one of the center links of the chain; and a source of electrical energy for energizing the strain sensing unit, the signal conditioning unit and the radio frequency transmitter.
