	Depends on the numeric value of 'really high'.

	And lots of them.  Distribution at 14kv and down is
	one thing.  Transmission at 100KVAC and up (standards
	at 350, etc) are common.

	'everywhere'.
	(Ferinstance, some of the power i use to send this
	arrives from Canada, via a +/-500kvdc line.  Which
	is insulated and can, on exception, be operated as
	1 MV to ground.)

	And the forests of NE, and elsewhere.

	is the publisher for, among others, Electrical World.
	Either of these might well have _data_.

	And, yes, LV to get the power 'to the customer' is
	the majority.  Getting it TO those lines, ALL the
	power goes thru the high lines, with minor
	exceptions.
