Composite grounding communication optical cable
An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The. HistoryAn OPGW cable was patented by BICC in 1977 and installation of optical ground wires became widespread starting in the 1980s. In the peak year of 2000, around 60,000 km of OPGW was installed worldwide. Asia, especially. Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack lengt.

10kV busbar section grounding fault
When the electrical bus bar insulator suffers insulation damage, it can lead to a ground fault in a 10kV busbar at best, and a phase-to-phase short circuit at worst, causing extensive power outages and potentially severe consequences to the distribution network. The high magnitude fault currents require high-speed operation of the busbar protection to limit equipment damage. The proposed scheme successfully detects single-phase-to-ground busbar faults by using the standard settings of the wide y available overcurrent IEDs, and an IEC 61850 communication between them. Additionally, ferroresonant overvoltages (several times normal voltage) may occur, breaking down insulation and causing major. Also, in the case busbars sections are separated, only one section needs to be isolated to clear a fault. Busbar protection is actually the strongest when bus sections are separated.
