Potential transformers are standard fare in power substations.
These are potted transformers with a core configuration very
similar as those used for step-up xfmrs in X-Ray machines.
These transformers are constructed to exacting specifications and
are used to connect sensor equipment to HV lines in order to
monitor voltages. The primary/secondary turns ratios are precise.
I have also seen these transformers in substations stepping down
a kilowatt or two to run cooling fans on the heavy 3 phase step-
down transformers.
