Correction factors
6.2.9.1
VT ratio correction
The operation of some regulators is such that the internal VT does not provide the desired
voltage ratio. In these cases, it is desirable to correct the VT secondary voltage to a 120
Vac reference base. This change is easily made in software, eliminating the need for a
multi-tap sensing transformer.
The correction is derived from information provided by the regulator original equipment
manufacturer (OEM). The numerical value of the correction is the value, in volts, required
to adjust the VT nominal secondary voltage to 120.0 volts. The correction range is ±15
volts in 0.1 volt increments.
The maximum allowable continuous VT secondary voltage is 140 volts.
The correction is made only in software. As a result, the value of VLoad
read on the control display will differ from that measured at the voltmeter
test terminals by the percent of the correction voltage.
