Simply measuring the current, there is no difference between one ampere of 10,000 volts and one ampere of one volt because it only means that one ampere of current passes through a

For three-phase electric meter, there are three wires and four wires electric meter. In three-phase four-wire system, in the low-voltage distribution network, the transmission line

Smart meters make people's lives more convenient and power enterprise management more efficient. But we also have many questions when we use the meter, such as: A: Do you know?

In the previous article, we talked about smart meter consumes power all the ways but not on the user's wallet. So, the question comes to why we feel we consume more power after

With the development of 5G up to now, no one knows where and which fields it will be applied in the future, but some places that require data support will definitely be able to use

Recently, the global energy prices have continued to rise, the supply and demand situation has been tense, the prices of natural gas, thermal coal, and oil have soared, and electri

Traditional grids are aging and can’t meet the increasing demand for growing electricity. Governments are struggling to build up a smart grid. Why smart grid so important at the na

When the photovoltaic inverter converts the direct current generated by photovoltaic modules into alternating current, it will be mixed with direct current components and harmonics

Smart lights and thermostats are popular in commercial buildings and when they combine with the energy management system, energy bill savings are without effort on the user’s side.

IoT technology plays important role in energy saving. Such as in controlling temperature. A conditioner with learning thermostats will precool or prewarm the space before the heat

1. Reduce the management cost of power collection. The remote centralized reading of electric energy meters has changed the outdated manual meter reading mode, reduced the labor in

RS 232 was born earlier before RS 485. But it has deficiencies. 1. The signal level of the interface is relatively high, reaching more than ten V, which is easy to damage the chip
