Q : What is the insulation level of this transformer?
R : The spec does not provide insulation level; it is [On Request].
Q : Can this transformer be used for voltage measurement?
R : No, it is a power transformer for control power, not a voltage transformer for metering.
Q : Is the primary voltage selectable?
R : Yes, the primary can be connected for 20kV or 15kV as per the spec.
