Description

technical field [0001] The invention relates to the technical field of electrical measurement, in particular to a non-contact electric quantity measurement and recording device. Background technique [0002] In recent years, with the vigorous development of large-scale equipment and mobile robots, developers and maintenance personnel have increasing demands on equipment power changes and power supply performance changes. Therefore, it is necessary to accurately measure and record the voltage and current of high-power systems during operation. The development and maintenance personnel calculate and analyze the load change during system operation according to the power change curve and current and voltage change curve, and carry out fault diagnosis and analysis, so as to optimize the stability of the system power supply. [0003] However, current solutions for measuring system current and voltage are usually plug-in or integrated, that is, the measurement device is connected i...

Problems solved by technology

[0003] However, current solutions for measuring system current and voltage are usually plug-in or integrated, that is, the measurement device is connected in series with the system under test to measure the current and voltage of the system under test. This solution is simple in design, but has the following Disadvantages: On the one hand, the integration of the measuring device increases the complexity of the system. When there is a problem with the measuring device, it will cause the circuit of the system under test to fail; on the other hand, when measuring a large current for a long time, it will affect the electrical safety of the measuring device Performance puts forward higher requirements, and the embedding of measurement devices will also increase the power consumption of the system
