Measurement transformer settings

Set the following parameters at the integrated 
measurement transducer:

•  Compensate for the influence of the coil lengths 

through the potentiometer switching (1). To do 
so, set the parameters according to the table:

Measurement range

DIP switch

100 A

8

250 A

7

400 A

6

630 A

5

1000 A

4

1500 A

3

2000 A

2

4000 A

Setting

Rogowski coil

600 mm

Flex-CT-1A-600 mm

•  Set the current measurement range with the 

DIP switch (2) in accordance with the table:

Potentiometer

(1)

DIP switch

(2)

- 6 -

•  The transformer ratio should be adapted in the 

UMG 512-PRO measurement device too in 
accordance with the table. Change the settings 

•   by means of the GridVis software or
•  by entries on the device (measurement 

range: ratio 

x

 

/

 

1 A

 ). 

Please refer to the UMG 512-PRO operation 
manual for this.
