Analysis of Characteristics of Digital Display Multifunctional Electric Power Meter

The digital display multi-function power meter is independently developed and is a multi-functional intelligent instrument with programmable measurement, display, digital communication and power pulse transmission output. It can complete power measurement, power measurement, data display, collection and transmission. It is multi-functional. Power instruments are widely used in substation automation, distribution automation, smart buildings, and internal power measurement, management, and assessment within enterprises. Any equipment may "go on strike", and power meters are no exception. Is it too annoying when something goes wrong?

Features of digital display multi-function power meter: As an advanced intelligent and digital power grid front-end acquisition component, the multi-function power meter can be used in energy management systems, distribution automation, smart buildings and smart switch cabinets; it can be used with high Accurately measure all commonly used power parameters in three-phase power grid systems: three-phase voltage, three-phase current, active power, reactive power, power factor, grid frequency, active energy, reactive energy, with a variety of wiring methods, and with Communication interface and power pulse output function. Realize LED on-site display and remote RS-485 digital communication. It has the characteristics of easy installation, simple wiring, convenient maintenance, small engineering volume, and on-site programmable setting of input parameters, which can meet various on-site requirements.

How to repair or test a powerful multi-function meter! The following editor will talk about "How to repair a digital multi-function power meter? Let the faulty meter and the normal meter run under the same conditions, and then detect the signals at some points Then compare the two sets of measured signals. If there are differences, you can conclude that the fault lies here. This method requires maintenance personnel to have considerable knowledge and skills. It is required to have two instruments of the same model, and one of them is operating normally. .Using this method also needs necessary equipment, such as multimeter, oscilloscope, etc. According to the nature of the comparison, there are voltage comparison, waveform comparison, static impedance comparison, output result comparison, current comparison, etc.
