Electrical system inspection refers to the regular or periodic examination and evaluation of various components of electrical equipment and systems to ensure their safe, reliable, and efficient operation. This process includes checking the physical condition, electrical parameters, connection points, insulation performance, protective devices, and other aspects of electrical equipment. Here are some common inspection contents and methods:1. Physical InspectionVisual Inspection: Check the appeara

Purpose of Using High Voltage and Low Frequency in Power SystemsThe main purpose of using high voltage and low frequency in power systems is to improve transmission efficiency and reduce costs. Here are the specific reasons:1. High Voltage Reduce Current: According to Ohm's law V=IR, increasing the voltage can reduce the current. Under the same power transmission conditions, higher voltage means lower current. Lower Line Losses: Line losses are proportional to the square of the current, i.e., Pl

Differences Between Fuses and Circuit Breakers in Surge ProtectionIn surge protection, fuses (Fuses) and circuit breakers (Circuit Breakers) are both important protective devices used to prevent damage to circuits and equipment caused by overcurrent and surges. However, they differ in their working principles, response times, and application scenarios. Below is a detailed comparison of fuses and circuit breakers in surge protection:1. Working PrinciplesFuses Principle: A fuse is a fusible elemen
