The measurement of the tap changer position via MIM module is based on the
principle that the specified mA input signal range (usually 4-20 mA) is divided into N
intervals corresponding to the number of positions available on the tap changer. All
mA values within one interval are then associated with one tap changer position value.
The number of available tap changer positions N is defined by the setting parameters
LowVoltTap
and
HighVoltTap
, which define the tap position for lowest voltage and
highest voltage respectively.
