Abstract

The invention discloses an electronic measurement method with compound functions. The method includes setting an electronic gauge, and setting a functional test unit and a central processing unit which are connected mutually inside the electronic gauge; setting a multimeter test module, a leakage switch detecting module and a harmonic analysis module in the functional test unit; setting a software control platform; and powering up and starting working, wherein the functional test unit starts to collect information sent by an information source and transmits the information to the central processing unit after collection; and the central processing unit processes and outputs the information. The invention further discloses an electronic measurement device with the compound functions. The electronic measurement method and device with the compound functions combine functions of multimeters, leakage switch detectors and harmonic analyzers together, the measurement is fast and convenient, the device is convenient to carry, the utilization is intelligent, and measuring accuracy is greatly improved combined with the additional functions.

Description

technical field [0001] The invention belongs to the field of electronic information and relates to electronic measurement technology, in particular to a composite function electronic measurement method and a composite function electronic measurement device for realizing the method. Background technique [0002] The root cause of harmonic generation in power systems is due to non-linear loads. When the current flows through the load, it does not have a linear relationship with the applied voltage, and a non-sinusoidal current is formed, that is, harmonics are generated in the circuit. DC transmission and high-power single-phase rectification technology are widely used in industrial sectors and electrical equipment. Leading to current waveform distortion and three-phase imbalance become increasingly serious, becoming an important factor affecting power quality. Impulsive power loads (such as electric arc furnaces, DC transmission converter stations) put into operation on the...
