Abstract
The invention discloses an electricity measurement system for a cable clamp. The electricity measurement system comprises an induction circuit module, a functional control module and a marking circuit module. The induction circuit module comprises an induction probe and a electrified display piece. The output end of the induction probe is electrically connected with the input end of the functional control module. The output end of the functional control module is electrically connected with the input end of the electrified display piece. The marking circuit module comprises an input circuit and a marking display piece. The output end of the input circuit is electrically connected with the input end of the functional control module. The output end of the functional control module is electrically connected with a liquid crystal display screen. The induction probe induces that a cable is electrified and then transmits an electrical signal to the functional control module. The functional control module judges the electrical signal, controls the electrified display piece to be lightened according to the judgment result, and sends out an electrification warning. By defining cable switching of the input circuit and displaying the mark of the cable on the marking display piece through an internal program which is arranged in the functional control module in advance, potential safety hazards caused by temporary protection are eliminated.
