View Post: Mishap at the Electrical Substation - Boing Boing
20 Nov 2009 by Maggie Koerth-Baker  
When a circuit is opened and the wiring or loads constitute inductance, the magnetic field collapses all at once and very high voltages are the result. If resistance was zero the voltage would be infinite hence the arcing. ...

20 Nov 2009 by HDK  
With cables, the electric field is eliminated whereas for OHLs, the maximum exposure under a line is around 5000V/m falling to around 50V/m at 100 metre distance. Both OHLs and UGCs produce a magnetic field. The magnetic strength at 1 ...
