Similar in Auckland, Mike.
A few new 11 kV regulators have been installed on long spur lines to keep the voltage within limits.
Also some 11 kV lines have been upgraded to 22 kV, with new insulators and transformers. At halfwaypoint a 22 / 11 kV transformer will feed the rest of the line, so not all equpment had to be replaced and reduce some costs.
CBD Auckland used to run on 6.6 kV. Has been upgraded to 22 kV now.
Also the new 22 kV switchgear is not much bigger at all, or the same in size as 11 kV gear.
Cheers, Raymond
