Design High Sensitivity Differential Current Transformer

Hello. I had to build prototype that has to be able to measure relatively small changes of current flow ( 10-100uA in 10A current sensor and deal with problems this sensitivity gives. Can You reveal some details of Your project to me? For example - maximum current, maximum current sensitivity, voltages, working frequency and signal waveforms? Respectfully, ArtVil

hi, i am an electrical engineer and an embedded system designer.i have experience with designing Low power and high power Grid transformers. The bid quoted here is not final it just to create a communication channel with you. i would like to discuss the project details further with you so i can understand your requirements and the appropriate bid can be quoted afterwards. Looking forward for your reply.

Hi i can help you , is very important you specified I current 1, 2 ,5, 10, 50 ,100, or more Amp , for samples of works see portfolio

I have designed a number of products ranging from RF & Microwave circuits to digital circuits. i have experience in designing filters, couplers, LNAs, Amplifiers, antennas, sweep generators, function generators, VCOs, NCO and many more in the frequency range of DC to 2 GHz. i use ADS, HFSS, OrCAD, Eagle PCB for the design and development of the above mentioned products. I have designed circuits for Filters, Couplers, LNA, Amplifiers, Antennas, Bluetooth, Wifi, Sweep Generators, Function Generators, VCOs, NCOs, DDS, 555 timers, AM Modulators, Microcontrollers, EEPROM, Flash, Accelerometers, RTC, Strain Guages, Opto-couplers etc. My area of expertise include also PCB Schematic and Layout Design, Antenna Design, PCB Prototyping and testing, Programming using LabWindows, LabVIEW and MATLAB, etc. Please give me further details about the pr

Dear Please provide me more with you'r requirements, what exactly do you want to be designed, from you'r project i can't determine what exactly do you want to be designed, the transformer itself or something else, please fell free to contact me.

hi i can adivse on this i did ground leakage protection device before it use differential current transformer to detect current disbalance in 110..220 V AC power device

Waiting for +ve reply

Professional Electrical engineer working in Power sector industry having in depth know how of differential transformers made by Siemens and GE. inbox if interested. will help you out till the end. Remember I am a professional engineer.

Hi, I'm a mechanical engineer and an inventor. I will like to design this device for you. Lets discuss more in private message. Thanks, Sean.

hi , i am ready to work with you on least amount while giving you better quality then any other one !! the reason is just to create a long term realtions with you and your organization !! i am having more then 5years experience of development and designing on various platforrms like : PHP,JAVA,.NET,PLC-SKADA,EMBEDED,ROBOTICS,PCB DEDESIGNJOOMLA,WORDPRESS,HTML,UI/UX,PHOTOSHOP,C,C++,C#,DRUPAL etc.

Hi, I have been a hand on consultant to many businesses designing electronic/electrical circuits and substituting,etc. Some factories I have worked with are Cocal-Cola, Pepsi, British America Tobacco, etc. I am a GE group (Videojet) certified service engineer (ISO-9001) training and I am an Electronics/Programming/Hardware/Microcontroller/Microprocessor,Communications (RF/VOIP/GSM) expert or at least very good. I am a Canadian business technology developer. I own the business and I do the hi tech stuff. I really dont understand your requirement/application, but I know I can help you. I am VERY HIGHLY skill in all technologies with loads if experiences/exposure. Do you want to build a differential detector to shut down a system if one or mor phaze(s) fails or has a brown-out, etc? If so then we need to build something which can be tailored to respective environments. I.e. A detector in California might not work well in the North of Canada. Electrical tolarences are different. If I am on the right track I think your approach should be a digital one (micro controller) so that you can program tolerances to suit each environment. If it is something else that you want let me know and I will see if we can do this together. I love doing cutting edge stuff! By the waym I require a minimum of 25% advance/confirmation fee for all work I undertake. Thanks Anthonus.

I offer you 30 years in electronics, expertise and experience outsourcing design services since 1996. My apologies, the project description is so generic that we can't evaluate the task please send us a project specification or open a chat to know more requirements. We reserve the rights of withdraw this proposal until have a full project specification. Best regards Walter

I think that I could solve for you this project. I read recently a very interesting article regarding this subject.

Hi! I am an experienced hardware designer with advanced knowledge in energie measuring. In my last job I had to studied and reverse engineering many devices which can measure power consumption and I designed an energie measuring system. Please provide further details of your project and describe more precisely, if it could. I need more information to estimate a proper cost and duration for the job. (Please note that my offer can be changed.) Kind regards, Zoltan

I specialized on power electronics at undergraduate program @METU/Turkey. I believe I can do your project carefully. I request from you to give information about project. Sincerely,

Gentlemen I am an Electrical Engineer with almost 40 years of experience with a large background on power control. To present you further details of my proposal and how I intend to devellop this project it is very important for me to know exactly and with more details your problems and your requirements and wha data we are able to provide me to in order I can work with solid technical bases. Of course I will keep confidential every single data you will provide me. Please accept by best regards. Manuel Bolotinha
