-
01Highest voltage for ALH current transformer?
It can be used for AC low voltage up to 720V.
-
02Is protective class product available for the ALH current transformer?
Yes, available for both II-P and III-P.
-
03Maximum primary current of the ALH current transformer?
8,000A.
-
04Is open circuit allowed on the secondary side of the current transformer?
No, it is strictly forbidden.
-
05Common accuracy classes for the measurement current transformers produced by APT?
Five: 0.2S, 0.5S, 0.2, 0.5, and 1.
-
06Difference between accuracy classes with "S" and without "S"?
Accuracy classes 0.5S and 0.2S are generally used for metering, while 0.5 and 0.2 are generally used for measurement.
-
07Maximum primary current that can be detected by a measurement current transformer?
1.2 times the rated current.
-
08Current standard implemented for our current transformers?
The latest national standard is GB20840.
-
09What do P1, P2, S1, and S2 stand for in a current transformer?
P1 and P2 are the primary polarity terminals, and S1 and S2 are the secondary polarity terminals. P1S1 and P2S2 are the corresponding terminals with the same name. Typically, P1 is positive and P2 is negative. If the wiring of P1 and P2 is reversed, then the corresponding S1 and S2 should also be reversed.
-
10Operating altitude for our current transformers?
In accordance with GB20840.2-2014, at altitudes up to 1,000m. Above 1,000m, derating is required for use.
