Amendments to VDE 0126-1-1 and IEC 6210 define the design and procedures needed for such systems : primarily, ground current measurement and DC to grid isolation tests.

The first official SANFL night game was played at the oval on 21 April 2011 with the Panthers defeating Port Adelaide in front of the grounds current night attendance record of 2, 700.

The grounds current capacity is 10, 000 well below the record attendance OF 23, 500 set on 22 May 1949 when it hosted the French rugby league championship final between AS Carcassonne and Marseille XIII

Sometimes the ground braids are only connected to earth ground at one end of the line, to avoid ground current travelling over the braid and having a " ground loop . " talk ) 17 : 14, 5 August 2009 ( UTC)

When a CME impacts the Earth's magnetosphere, it temporarily deforms the Earth's magnetic field, changing the direction of compass needles and inducing large electrical ground currents in Earth itself; this is called a geomagnetic storm and it is a global phenomenon.

These statistics do not reflect the difference between direct strikes, where the victim was part of the lightning pathway; indirect effects of being close to the termination point, like ground currents; and resultant, where the casualty arose from subsequent events, such as fires or explosions.
17.
The lights have seen an increase of attendances at the ground with the first game under lights attracting the grounds current record night crowd of 6, 133 for the opening game of the season with West defeating North Adelaide 14.19 ( 103 ) to 4.7 ( 31 ).

The main benefits of fiber are its exceptionally low loss ( allowing long distances between amplifiers / repeaters ), its absence of ground currents and other parasite signal and power issues common to long parallel electric conductor runs ( due to its reliance on light rather than electricity for transmission, and the dielectric nature of fiber optic ), and its inherently high data-carrying capacity.
