About this unit
Pre-owned 1990 Northern Transformer unit stepping 44 kV down to 4,160 V. LTL, a Toronto supplier of utility safety and testing gear, lists it in its pre-owned transformer table and asks buyers to call for pricing. A second entry (INV 44, serial 90-670) repeats its data but says 250 kVA while its drawing file says 2,500 kVA; ask whether there are two.
