Although the technology level of today is high than yesterday, electricity is still an important source of national development and social stability. The rapid growth of power dist

First, we need to buy qualified test pens in regular stores. Then, when using a physical stylus, the position of the stylus is important: index finger against the cap end of the st

We often use a test pen to test electrical appliances to determine whether they are installed correctly. Today we will introduce the functions of the test pen. * To test whether th

* Before using the test pen, first, check whether there is a safety resistor in the test pen, and then visually check whether the test pen is damaged, whether it is damp or water,

One of the important supports in the global information age is smart water affairs, and smart water meters are an important part of the new generation of information technology. Ut

When the electricity is used normally, the trip indicator is in the "sleep" state for a long time. When the balance is low, the indicator light flashes and the indicator

When we are looking at smart meters, like single-phase Wi-Fi energy meters, Wi-Fi wall-mounted energy meters, three-phase Lora WAN electric meters, etc., the most conspicuous thing

In December 2021, there was heavy snowfall in the Liaoning area. A large number of module arrays at a local photovoltaic station were crushed or damaged by the university, resultin

For single-phase or three-phase smart meters, we often read the below parameters on the electric meter manual: 5(60)A, 220V, 50Hz, 1200 imp/kWh. What are they meaning? 5A is the re

Due to the poor mechanical strength of a single solar photovoltaic cell, it is easy to cause cracks in an outdoor environment, and at the same time, moisture and corrosive gases in

We use the crystalline silicon cells mainly used in the market to calculate, and now the market is divided into single-sided glass photovoltaic modules and double-sided glass photo

The density of glass is about 2.5 tons/cubic meter. Using the calculation formula of physical mass m=PV, it can be calculated that one square meter of glass with a thickness of 2.5
