V
mult
= 7620/(117 + 3) = 63.5
The voltage multiplier setting range is from 0.1 to 3260.0 in 0.1 steps.
The current multiplier is the value of the line CT primary rating divided by 0.2 A. For a CT
primary rating of 1000 A, the multiplier is:
CT
mult
= 1000/0.2 = 5000
The current multiplier setting range is from 1 to 32600 in 1 step increments.
Normalizing Voltage Multiplier
A Normalizing Voltage Multiplier with a range of 0.80 to 1.20 is available to be applied
to Meter Out Voltage and displayed in real time as Normalizing Voltage. The purpose of
the Normalizing Voltage Multiplier is to allow the user to overcome differences in the
ratio of the PT that the Meter Out Voltage input is using versus the PT the end user or other
metering methods are using.
6.2.7.2
Setting the Voltage and Current Multipliers from the HMI
The current input to the control is rated at 0.2 A continuous, 0.4 A for two
hours, and 4.0 A for 1 second.
The CT Multiplier selection in the Configuration/CT and VT menu only
changes the scaling factor for current reading and setting.
1.
Press the Down Arrow (CNFG Hot Button) pushbutton to wake the unit. The menu
will advance to "CONFIGURATION".
2.
Press the Down Arrow pushbutton once. The unit will display the following:
Tapchanger Type
3.
Press the Right or Left arrow pushbutton, as necessary, to navigate to the
"Nameplate" menu.
The following sequence of steps provide direction for setting the
Current Multiplier. The steps necessary to set the Load Voltage,
Source Voltage and Normalizing Voltage multipliers are similar.
