Illustration A shows the current setting.
CT rated current (Ict):
current transformer (CT) primary current. It is the upper value of
t
he CT
range divided by the feed-thru factor. The feed-thru factor
is how often
the primary conductor is fed through the CT. For
s
ingl
e
conductor
CT
the value on the label used. The
m
aximum allowed C
current is 6400A.
Table below shows the CT rated current in Ampere for different CTs and feed-thru factors.
Motor rated current (Ir):
settable in the range of 1 to 1/6 x Ict. This value is used for overload,
ground fault, and current thresholds protections
Two Speed motor:
only applicable for two-speed motors (Dahlander, Pole changer typicals).
When applicable a second CT and motor current can be set for the
additional speed. All other parameters are applicable to both speeds.
Phase:
select the system type: 3-Phase, 2-Phase, and 1-Phase.
