CT Coil & Multifunction Meter

"...its way less...", by a factor of 40? Where are you taking your readings, and what are the exact settings on your MF meter?

Am taking readings from MF METER , i think the factor of less than 10 because iR,iY,iB was around 73,85,93 amps respectively the reading from MF meter were approximately 1.345,2.565,2.676 amps i havent taken the reading from clamp meter!! Even if i did am sure it shows exact figures as PF controller does! Settings on the meter were all default i havent changed anything!!

Get a clamp-on ammeter and measure your phases and compare with the CT reading.

Am sure reading from clamp meter would be correct and MF METER displaying wrong values coz theres a 1 150 hp motor running for ibt coils and 2 50hp motor running for homogenizer they all literally suck up heavy juice up to 360 amps while starting and comes down to less than 50a so each phase is running at 80% capacity! My doubt is why is the brand new meter showing wrong values which is also CE certified and calibrated to show true RMS!!

Please find MF Meter part number & get manual of it. You will be able to find out your matter.

Your comment saved me, the dafault primary ratio of ct was on 5amps on MF meter i dint know this now i have changed to 233 now everything is working fine , thank you for manual heads up, how do i mark this thread as solved?

Nice that you responded and thanked for giving a correct solution. Many members do not even respond after many members give very good solutions after sparing their valuable time.

HI, how can i not convey my regard without thanking everyone,they just helped me to think from all angle, and sorted my own issue,forums are just wonderful places with wonderful helping Minds!!!!

It would be easier to understand this post were some punctuation provided. Without it, the post is difficult to understand, and the problem lies buried in misunderstanding. Compare, for example:

• "Let's eat, grandma.", and
• "Let's eat grandma."

The presence or absence of the comma completely changes the meaning.

Please re-post using appropriate punctuation.

sorry, am typing and posting everything from a mobile so its very hard even for me to go back and change anything like the typing cursor is not showing i cant know where i am selecting so i just type and post it ...

Next time, don't buy cheap Christmas Crackers.

lol, there is atleast 1 person in every forum who complains about everything other than doing some actual help....

Good one. Another story , one error in placing the coma in wrong place in judgement spared a life.

"Hang him, not leave him" Instead " Hang him not, leave him".

Are you connecting the CT's in series with the the conductors? From what I read from your description, you said you connected the CT's across the lines. Usual scaling Ct's are connected like hook-on's. Regular CT's you have to open the line and and connect the CT between the open line ends. If you are connecting the CT's between the phases, the reading will be astronomical since that would constitute a short circuit connection. Utility mains almost always are magnetic flux step down or scaled down types and have to be inserted in series with the current carrying conductors not across the conductors.

Ya well, like PWslack said you too misunderstood my meaning,am connecting the CT across each phase (RYB) separately like a regular CT only!!
