Setting the Volts and Current Ratio
Use this menu to add a ratio factor to the voltage or current input on each phase.
Changing the first “1” in each case if there is a potential transformer in series with the
voltage connection such as when you want to monitor a medium-voltage network using
PTs and CTs to scale the voltage and current to a convenient level for measuring
instruments.
The current ratio applies a ratio to the current input in order to show the current present
on a medium-voltage network. This feature is intended to be used for sensing low levels
of current to represent the much higher levels on the primary side at a substation or
step-down transformer that has built-in metering current transformers.
