Micom 633 Operating Data Measurement

Micom 633 Operating Data Measurement

(OP)
Hello,

In our Micom P633 transformer relay, we could not get the "Idiff" and "Irestain". The rest of the measurements are ok. I could be looking as the wrong group as it is on 'FT_DA' (which is fault recorder).

If I extract setting in the setting file than I could see the actual reading of 'Idiff' and 'Irestrain' (which I confirm from the relay local LCD display). Kindly refer to the attachment.

As per the manual, if the minimum threshold is not reached the value cannot be viewed and there should be indication "not measured', but in my case the 'Irestrain' looks like not in minimal value.

There is also possibility that the Micom Studio software I am using do not have this feature.

Any experience on this would be a great help.

Thanks in advance.
