How to Use a Power Meter1. Connecting the CircuitBefore using a power meter, connect it to the circuit under test. Pay attention to the following points during connection: Select an appropriate measurement range based on the characteristics of the circuit. If the voltage or current in the circuit exceeds the meter's range, it may result in significant errors or even prevent measurement. Ensure correct connection of the current and voltage input terminals to avoid wiring mistakes. For measuring A

Power monitoring systems undertake the core tasks of real-time grid monitoring, fault diagnosis, and operational optimization. Their security directly affects the stability and reliability of power systems. With the deepening application of technologies such as cloud computing, the Internet of Things (IoT), and big data in the power industry, information security risks for power monitoring systems are gradually increasing.These systems face multiple challenges, including advanced persistent thre

1. Principles of Ultraviolet Imaging TechnologyUltraviolet (UV) imaging technology leverages corona discharge and other localized discharge phenomena, which occur when the local voltage stress on a live conductor exceeds a critical threshold, ionizing the surrounding air and generating corona. During power equipment operation, corona, flashover, or arcing often arise due to design flaws, manufacturing defects, improper installation, or inadequate maintenance. In such discharges, electrons in the

A power system is a large-scale network composed of numerous interconnected components, including generation, transmission, substation, distribution, and end-user equipment. Failures in electrical equipment can not only lead to unexpected outages and financial losses for power utilities, but also cause significant economic damage to consumers. Therefore, the reliability and operational status of these devices directly determine the stability and safety of the entire power system, as well as the

Role and Selection of Microcomputer Integrated Protection Devices in High-Voltage SwitchgearIn recent years, the application of microcomputer integrated protection devices in medium- and high-voltage power distribution system projects has increased significantly.

What is a microcomputer protection device?Answer: A microcomputer protection device is an automatic device that can detect faults or abnormal operating conditions in electrical equipment within a power system, and act to trip circuit breakers or issue alarm signals.What are the basic functions of microcomputer protection?Answer: Automatically, rapidly, and selectively isolate faulty equipment from the system by tripping circuit breakers, ensuring non-faulty equipment resumes normal operation qui

I. BackgroundWith the advancement of intelligent power systems, microcomputer protection devices have become core components in modern industrial power distribution systems due to their high precision, multifunctionality, and reliability. Taking the power distribution project of a natural gas recovery station in the Middle East as a case study, this paper explores the critical role of AM series microcomputer protection devices in enhancing system safety, reliability, and automation levels, and a

Time relays are commonly used industrial control devices. Based on their timing characteristics, they can be classified into three types: on-delay, off-delay, and combined on/off-delay relays. Among these, on-delay time relays are the most widely used and readily available in the market. However, many on-delay relays have a limited number of contacts and only provide timed contacts without instantaneous ones, which poses inconvenience for electrical control circuit designs requiring immediate re
