The invention discloses an electric power instrument wiring fault detection method suitable for a reactive compensation power distribution room. The method comprises the following steps: S1, installing an electric power instrument of the reactive compensation power distribution room and electrifying the electric power instrument; S2, measuring a three-phase voltage phase angle; S3, judging whetherthe voltage wiring is correct or not to obtain a correct voltage wiring mode; S4, measuring a three-phase current phase angle; S5, calculating a three-phase phase angle difference of the to-be-measured object; S6, judging whether the current wiring is correct or not, and completing the detection of the wiring fault of the electric power instrument. The detection method provided by the invention mainly aims at an electric power instrument in a three-phase four-wire system mode. Whether voltage wiring is wrong or not is judged through a voltage phase angle, and whether current wiring is wrong or not is judged through the angle difference of voltage and current phase angles. The judgment method is simple and easy to operate, can effectively solve the field wiring problem, has practical operability, and meanwhile improves the wiring efficiency of installation personnel for installing the electric power instrument.
Description
technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a method for detecting wiring faults of power meters suitable for reactive power compensation distribution rooms. Background technique [0002] With the development of science and technology, smart multi-function meters are widely used in various places. Smart multi-function meters are responsible for the tasks of data collection, measurement and transmission. Therefore, the failure of smart multi-function meters directly affects the energy management system and the information of operators. judgment and analysis.
