Primary circuit test accuracy

(23 C ± 3 C, below70% RH) 0.0mA-9.99A: ±1%±5dgt 

10.0A-49.9A: ±2%±5dgt 

50.0A-199.9A:±3%±5dgt

200A-600A:   ±4%±5dgt   

601A-1000A:  ±5%±5dgt  

Secondary circuit test accuracy 0.00mA-10A: ±1%±5dgt (three-channel being displayed in one screen)   (23C±3C less than 70%RH)

CT ratio Three kinds of transformation ratio indications :

(1)convert the transformation ratio based on the adjustable basic value of 5A for secondary circuit current; (2)convert the transformation ratio based on 10kV-YY of 10kV/380V, that means 1st means the current of the line under 380V, 2nd means the secondary circuit current of CT under the 380V, and then calculate the ratio between the 10KV line and the secondary circuit;

(3)the measured current ratio can be calculated by the measured CT ratio between the primary and secondary circuit)

ReferenceRange Reference range of transformation: 0.00A ~ 99.99A, the default secondary circuit  current is transformed to 5A;

Range of Ratioerror

(F.Er) 0.0% ~ 9.9%, the error between the measured CT ratio and the preset CT ratio

Range of CTratio 0000-9999/0.0A-9.9A
