Hi Antonio,

It looks like that was quite an impressive EHV testing facility in its day. 
In addition to what Jim Lux has already provided, photos #48 and #52 appear 
to be a resonant transformer. The output of these transformers are 
typically connected to HV series capacitor or a heavily capacitive load 
(such as a buried HV cable). An adjustable ballast inductance is used in 
series with the LV side of the transformer in order to resonate the system 
mains frequency. This causes the secondary  to then ring up to a very high 
AC voltage.

Also, in looking more closely at the large towers, they may in fact be high 
voltage resistive dividers. Or they may indeed be enclosed Marx (or 
similar) impulse generators. The picture you may be thinking about may have 
been the following one of a 100 meter spark from an impulse generator in 
Siberia (from Bazelyan & Raizer's book, "Spark Discharge"):

Thanks for sharing these very interesting pictures!

Best regards,
