2. Underground power line - Wikipedia

   en.wikipedia.org/wiki/Underground_power_line

   An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...

   The photo also shows an unrelated distribution transformer, which reduces 4160 V to 240/120 V. Closeup of overhead powerline sensor hanging from one phase of a 4160 volt powerline In the photos on the right, an antenna on the sensor transmits data to a communication device attached to a nearby utility pole.

4. Stray voltage - Wikipedia

   en.wikipedia.org/wiki/Stray_voltage

   The Haldersons claimed stray voltage from high voltage power lines hurt their 1,000 cow herd and lowered milk production. The jury found that Xcel subsidiary – Northern States Power Company – was "negligent with respect to the delivery of electrical service." The jury awarded $4.09 million for economic damages and another $409,000 for ...

5. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...

6. Electromagnetic radiation and health - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_radiation...

   A measure of the heating effect is the specific absorption rate or SAR, which has units of watts per kilogram (W/kg). The IEEE [ 8 ] and many national governments have established safety limits for exposure to various frequencies of electromagnetic energy based on SAR , mainly based on ICNIRP Guidelines, [ 9 ] which guard against thermal damage.

7. Optical ground wire - Wikipedia

   en.wikipedia.org/wiki/Optical_ground_wire

   OPGW can be used for distributed temperature sensing, helping identify potential trouble spots along power lines. This is valuable for detecting and locating faults, such as hotspots or damaged sections, before they lead to more significant issues. The optical fibers within OPGW enable utilities to monitor the health and performance of power lines.
