How to identify the current transformer in a distribution box

Upon opening a distribution panel, one can observe multiple current transformers inside. Some panels may contain only one CT, while others might have five or six. They all function by sensing current signals from the busbar; however, the applications of the measured currents. Installation Select an appropriate location: It is usually installed inside the distribution box, close to the power inlet side, in a place that is convenient for installation and maintenance. They sense the current on the high-current cable and convert it into a corresponding small current signal for instrument measurement and relay protection. CTs are two terminal equipment. The summation measurement is carried out wi...
