Rprim Specified primary winding resistance (only available if primary winding
resistance measurement is enabled for the test).
Possible values: 0 to 3000 ohms or soft key ?
1
.
Default: ?.
Class mult.
factor
Class multiplying factor.
This factor increases the assessment level for the ratio test. E.g. a class
multiplier of 0.5 means that the maximum accepted tolerance for the ratio
error is only half the standard tolerance.
Possible values: 0.25 to 1.00 or soft key 1.0.
Default: 1.0 (as set in the device settings: Main Menu, entry "Settings" ->
Setting Menu, entry "Misc. Settings").
Delta com-
pensation
Correction factor for the ratio measurement. This factor enables the ratio
measurement for CTs that are installed inside a delta winding transformer.
Possible values: Soft keys Ratio 1, Ratio 2/3 or Ratio 1/3.
Default: Ratio 1.
Choose "Ratio 1" if no correction is required.
Choose "Ratio 2/3" if input PRIM is connected to the two terminals of that
transformer winding, the CT is in series with.
Choose "Ratio 1/3" if input PRIM is connected to the terminals of a
transformer winding, the CT is not in series with.
1. If the question mark is entered for this parameter and a new test is started, the CT Analyzer
automatically tries to determine the value using its integrated guesser function (see chapter 7 on
page 131).
