PM8000 non relevant display of values

[sesa12489_bridg]

a PM8000 displays

I mean = 0.034kA

Power = 0.009MW

You can access to the files with the

PM8000 Pb unité sur val mesurées.zip - Box

L3 in Prague told us to change the resolution from 1.XXX to 1.X it is not the root cause because the kA and MW are still there. What is the right way to solve that issue.

Thanks for your help.

Have you tried to change the PT and CT primary and secondary so that the ratio is still the same,
For example:
PT primary: 1
PT Secondary: 1
CT Primary: 1200

CT Secondary: 1

Hello Charles,

Sorry for the late answer, the customer is still having the following display :

He used the parameters that you specified us in your previous answer. Unfortunately nothing has changed.

His iron core CTs are 2000/5A. And he confirmed that primary current is really 34 A (measured with a third party current probe).

Is there any firmware issue ?

He told me that one time the current was at 400 A by connecting the switch board to a test bench.

Could you help us because we are still in trouble according to the display on PM8000.

Best Regards.
