Current sense transformers are used to detect and measure current. There are two basic types of products: switch-mode transformers for power conversion applications, and precision-measurement transformers for instrumentation applications. Current sense transformers for power conversion applications are used to measure trends, peak values and average values rather than absolute values. These devices are efficient and dense, but do not offer a great amount of accuracy. They are available in a...

Who Took Our Poll?Top
Well, the built-in rectification in recent models results in AC to DC conversion eliminates profound amounts of labor during installation. This hammers the bottom line down quite a bit and this is great.
Optical current transformer technology is most influencing current transformer design. Due to the almost same accuracy over the entire range of measurement from mA to kA range.
Since current sensing is a proven technology, we can not specify any particular company. There are many players in the market. When package units are considered, you can trust companies like Siemens.
Applications and UseTop
Wide bandwidth true floating voltage measurements. Elimination of ground problems, nearly optimal device. Easier to construct compared to voltage probes. I love them. Not many understand these. Good for hunting noise currents. Limitless uses.
AC current measurements in AC induction motors, Auto transformers ,Heaters and rectifier transformers etc. ACCT. DC current measurements in the Silicon controlled rectifiers with DCCT and Shunt etc.
We have developed and are using DCCT to measure DC currents from 0 to 6000 Amps. Development work is in progress to measure 30000 Amps DC. We are also using 8000 Amps ACCT.
For recording the generator voltage build up characteristics & sudden load throw off characteristics.
Accuracy over a wide range of DC components. For automotive power seats lumbar motors draw from 0.3 amps nominal, stall at 3.5 amps. The same power wires are monitored for some heater and larger motors where it may go over 20 amps.
Plain and simple DC output reflecting the RMS value of the AC Current. Real RMS would be very helpful. Superb galvanic isolation is a must.
-Always spec your desired end result, such as % accuracy at a rated load across a given temperature and frequency range. -Give the supplier breathing room at both ends of the current range if higher accuracy isn't needed to prevent overly expensive cores. -Ensure you know if there is a linearity requirement along with the accuracy.
Always specify your application and environment to manufacturer; they can guide you in a better way. Openly discuss with them your problems.
If you need a quick response, choose carefully - some of these are designed to monitor loads over a longer time and do not react quickly.
Always buy from Standard companies as they are with up to date technology.
