2. Network analyzer (AC power) - Wikipedia

   en.wikipedia.org/wiki/Network_analyzer_(AC_power)

   The Westinghouse Anacom was an AC-energized electrical analog computer system used extensively for problems in mechanical design, structural elements, lubrication oil flow, and various transient problems including those due to lightning surges in electric power transmission systems. The excitation frequency of the computer could be varied.

3. Mean time between failures - Wikipedia

   en.wikipedia.org/wiki/Mean_time_between_failures

   The Mil-HDBK-217 reliability calculator manual in combination with RelCalc software (or other comparable tool) enables MTBF reliability rates to be predicted based on design. A concept which is closely related to MTBF, and is important in the computations involving MTBF, is the mean down time (MDT). MDT can be defined as mean time which the ...

   Even though a company will pay for NRE on a project only once, NRE costs can be prohibitively high and the product will need to sell well enough to produce a return on the initial investment. NRE is unlike production costs, which must be paid constantly to maintain production of a product. It is a form of fixed cost in economics terms. Once a ...

   The final rule requires transmission owners to conduct 20-year plans assessing regional electric transmission needs that would need to be revisited every five years.

6. Mean time to repair - Wikipedia

   en.wikipedia.org/wiki/Mean_time_to_repair

   Mean time to repair (MTTR) is a basic measure of the maintainability of repairable items. It represents the average time required to repair a failed component or device. [ 1 ] Expressed mathematically, it is the total corrective maintenance time for failures divided by the total number of corrective maintenance actions for failures during a ...

8. Underground power line - Wikipedia

   en.wikipedia.org/wiki/Underground_power_line

   Above-ground lines cost around $10 per 1-foot (0.30 m) and underground lines cost in the range of $20 to $40 per 1-foot (0.30 m). [10] In highly urbanized areas, the cost of underground transmission can be 10–14 times as expensive as overhead. [11] However, these calculations may neglect the cost of power interruptions.
