In electrical systems, grounding (grounding) primarily serves to provide a safe path for fault currents to be directed to the earth, protecting equipment and personnel. However, grounding is not the normal return path for current because there are distinct differences in function and design between grounding and the normal return path. Here are some key reasons:1. Safety Purpose1.1 Fault Current Dissipation Fault Protection: The primary purpose of grounding is to provide a low-impedance path for

Ultrasonic receiving circuit

Reducing the neutral-to-ground voltage (NGV) is an important measure to improve the stability and safety of electrical systems. High NGV can lead to equipment failure, electromagnetic interference, and safety hazards. Below are some common methods and techniques to reduce the neutral-to-ground voltage:1. Improve the Grounding System1.1 Optimize the Grounding GridGrounding Grid Design: Ensure the grounding grid is designed properly, using a sufficient number and length of grounding electrodes to

Basic concept In electricity, "bypass" refers to providing an alternative path for electric current to bypass a certain element, circuit, or part of a device. This alternative path is usually connected in parallel with the main path. When certain conditions are met (such as a signal of a specific frequency or a current exceeding a certain amplitude), the current will preferentially or partially pass through the bypass. Application scenarios Principle: In electronic circuits, a capacitor is
