2. Trace heating - Wikipedia

   en.wikipedia.org/wiki/Trace_heating

   Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels using heat tracing cables. Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe. The pipe is usually covered with thermal insulation to retain heat losses ...

3. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable), [1] and to locate ...

4. 25-pair color code - Wikipedia

   en.wikipedia.org/wiki/25-pair_color_code

   25-pair telco cable pinout. A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.

5. Reflections of signals on conducting lines - Wikipedia

   en.wikipedia.org/wiki/Reflections_of_signals_on...

   Contents. Reflections of signals on conducting lines. A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction ...

6. Electrical length - Wikipedia

   en.wikipedia.org/wiki/Electrical_length

   In electrical engineering, electrical length is a dimensionless parameter equal to the physical length of an electrical conductor such as a cable or wire, divided by the wavelength of alternating current at a given frequency traveling through the conductor. [ 1 ][ 2 ][ 3 ] In other words, it is the length of the conductor measured in wavelengths.

7. Field line - Wikipedia

   en.wikipedia.org/wiki/Field_line

   A vector field defines a direction and magnitude at each point in space. A field line is an integral curve for that vector field and may be constructed by starting at a point and tracing a line through space that follows the direction of the vector field, by making the field line tangent to the field vector at each point. [3][2][1] A field line ...
