Hi everyone.
I'm planning on building current clamp tester for my graduation project. We build hall effect current sensors on the company that I currently work at, recently we had issues with our quite rudimentary test rig. It's basically a short circuit that runs on a long wire that loops several times in order to reach the desired current, then we get our sensors and clamp them to such wire. Some of our beefiest sensors read up to 2000A.
I guess the main question that I have is how do these companies manage to provide such high currents (2400A) on what seems to be a small footprint for their products.
https://emsyst.com/portfolio/current-transformer-testers/I thought about using a VARIAC to control the current, an internal load and a coiled cable from which I would clamp the sensor to it. It would be good if I could manage to come up with a design that would
not need to use a loop of cables considering that not all of our sensors are clamp types, which means that I would need to physically loop the wire around the sensor instead of just clamping it to the loop itself. We provide sensors that measure both AC and DC, making the project even more challenging.
I'd really appreciate any suggestions, literature, tips, anything.
Maybe I'm just trying something a bit too complex for a graduation project.
