Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
The device has two antennas. One antenna collects data from the sensors, and the other antenna forwards the data to the electrical utility control center over cell phone service. In some systems, powerline sensors may transmit information on the high voltage conductor itself rather than by transmission of a radio signal. [4] [5]
Typically, the DLR server can be configured to send standard telecontrol frames to the electric utility's SCADA front-end acquisition units. These frames can then be processed for display and calculations by the utility energy management system or distribution management system. Short-term network operation decisions are based on optimized ...

Each utility has a unique set of business, regulatory, and legislative drivers that guide its investments. This means that each utility will take a different path to creating their smart grid and that different utilities will create smart grids at different adoption rates. [citation needed]
These services are known as Measurement while drilling and Logging while drilling. Information acquired thousands of feet below ground, while drilling, is sent through the drilling hole to the surface sensors and the demodulation software. The pressure wave (sana) is translated into useful information after DSP and noise filters.

[4] The primary driver for the automation of meter reading is not to reduce labor costs, but to obtain data that is difficult to obtain. [citation needed] As an example, many water meters are installed in locations that require the utility to schedule an appointment with the homeowner in order to obtain access to the meter. In many areas ...
