I assume there is specific software that can be used to monitor all different types of equipment. Thank you for writing such a great article about extending the life of the equipment.

Comment on Rogowski Coil Linearity and Accuracy with and without Integrators by N.L.C.A. Gunasekara https://www.magnelab.com/rogowski-coil-linearity-accuracy-without-integrators/#comment-2075 Sun, 21 Apr 2019 08:46:24 +0000 http://www.magnelab.com/?p=2017#comment-2075 Recently I bought two Three Phase Rogowski coil meters and I compared it with the readings of Digital Multifunctional meter reading. It is almost the same but with the Clampmeter it differs several amperes. Why is that?

Comment on How to Determine Core Size in Current Transformers by Neil Wuebker https://www.magnelab.com/how-to-determine-core-size-in-current-transformers/#comment-1952 Fri, 29 Mar 2019 16:36:31 +0000 http://www.magnelab.com/?p=1648#comment-1952 The VT of a current transformer is determined by the voltage on the output instead of the voltage on the primary. If you have a 5 amp output you will need to determine the load used on the secondary circuit to determine the voltage (V). The frequency of the primary signal determines the rate of change in time (T). These are also the factors used when determining the core cross section needed.

It varies with turns ratio, desired output and current rating of the primary.

I have difficulty measuring or calculating transformer core area. I want to build a 2000va transformer from a 2000va stabilizer transformer. How will I determine the core area of this transformer?. If this transformer would be a good match for what I intend to build, what sizes and number of turns of wire will i apply here?. Thanks

let say i have a 100/5Amp ratio ,input voltage 415volts on primary of CT ,
i am confused that what will be VT here and how much ?
also what should be flux density for a low voltage CT with 100/5AMP ?
also what will be stacking factor of core?
kindly explain ,thanx

I do not know who you are but certainly you are going to
a famous blogbger if youu are noot already 😉 Cheers!
