Application of surge protector in solar energy system
Surge is a term used to describe an increase in electrical current or voltage in an electrical system. In the context of solar systems, surge refers to a sudden increase in the amount of electricity produced by solar panels. One way that surge can occur in a solar system is through the use of solar panels that are connected in parallel. In a parallel connection, the panels are connected so that the positive terminal of one panel is connected to the positive terminal of another panel, and the negative terminals are similarly connected. This configuration allows for the production of more ele...Read more -
What is the working principle of the lightning protection surge module (surge protector)?
What is a lightning protection surge module (surge protector)? It is estimated that most electrical technicians are familiar with it. A surge protector (SPD) actually suppresses surge voltages caused by lightning, electrical system operations, or static electricity. Lightning strike is a natural phenomenon that may cause serious harm. It will not only cause great harm to people, livestock, trees, etc., but also seriously affect buildings and electrical and electronic equipment. Therefore, it is very important to install lightning protection devices. As a lightning ...Read more -
The application of rcmu in the detection of residual power (leakage current) of DC power supply equipment
Introduction: Power engineering DC power supply equipment, as the security power supply and control signal power supply of the main electrical equipment, is a very large multi-branch power supply network. Under normal circumstances, one-point grounding does not affect the operation of the DC system, but if the grounding fault point cannot be quickly found and repaired, another grounding fault occurs, which may cause major faults. There are two main methods for traditional detection of DC system insulation: bridge balance method and low-frequency detection method. B...Read more -
Basic principle of leakage current detection and selection of leakage current protection method in ev charger
First, the classification of leakage current Generally, there are four types of leakage currents: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current. 1. Leakage current of semiconductor components The very small current that flows through the PN junction when it is turned off. D-S is forward biased, G-S is reverse biased, and after the conductive channel is opened, current will flow from D to S. But in fact, due to the existence of free electrons, free electrons are attached to SIO2 and N+, re...Read more -

Science: How to choose electric car charging post, which is better to choose DC charging post or AC charging post?
What are the considerations for choosing an EV charging post, and whether it is better to choose a DC charging post or an AC charging post. From the consideration of using demand, the overall cost of DC charging pile is high, and the cost of AC charging pile is low. If it is a personal installation of charging piles, it is recommended to use AC charging piles. The charging power of AC charging piles can reach a maximum of 7KW, and it takes 6-10 hours to be fully charged on average, and the electric car will be parked directly after returning home from work and charged without delay the next...Read more -
