•A count of the number of times the control tap position indication (TPI) was synchronized
either at neutral or when the regulator was able to tap up or down when TPI was at 16R or
16L respectively.

•This is the actual percentage that the regulator is actively boosting (raising) or bucking
(lowering) the input (source) voltage.
•When the regulator output voltage is greater than the input voltage (regulator boosting),
the sign is implied (+). When the output voltage is lower than the input voltage, the
sign is implied (-).
•Tap position indication is calculated as follows: % regulation = [(output/input) - 1] x 100.
•During reverse power operation, the control requires source voltage from a differential or
source potential transformer or from the source voltage calculation (see FC 39) to obtain
this parameter. Lack of this voltage will result in the parameter displaying dashes.
