Non-contact self-powered clamp current transformer can be connected to only one conductor

Non-contact self-powered clamp current transformer can be connected only with a conductor without having screwed or welded to the bracket complex, so that the installation and maintenance easier. To avoid complicated wiring, these transformers can be installed in the electrical control panel to achieve the sometimes inaccessible or harsh environments running equipment for remote monitoring. Clamp  mcb circuit breaker  has the advantage without the need for a charging device can interfere with the operation of their reassembled into it, which often become engineers designed the clamp transformer power meter only choice. But these advantages there is a price to make than solid core current transformer  mcb circuit breaker  prices are more expensive, but also less accurate. Therefore, understanding the various techniques can be applied to the difference between the limiting conditions and in accordance with specific application to choose is very important. Clamp current transformer is usually based on the above  Electric transformer  solid core transformer. However, in this case, the core is composed of two distinct parts can be separated components. Uncertainty mainly from poor contact between the two parts, and the secondary winding around the core distributed unevenly distributed and only one of the two parts around it. The price and performance of these transformers and equipment of the physical and mechanical properties. Between the two parts of the core need to be very smooth contact surface and enough pressure. This is generally a sufficient clamping force generating member or a flexible material and / or a hinge mechanism and a reliable open characteristics.
