Programming the Turn Number:
Note:
If the voltage transformer is not used between the system
and EPR-04/04S, voltage transformer ratio is entered as 1.
Example:
Example:
If a voltage transformer which has a ratio of 34.5KV/100V
is used between the system and EPR-04/04S; Voltage transformer
ratio is entered as 345. (34500/100)
ratio is entered as 345. (34500/100)

the turn number, which is the number of how many tour the current
cable has rounded into the CT-25. Numbers can be selected
between 1-20. Greater the number of turn means greater the
sensivity.
