Safety Rules for Overhead Lines

The Critical Role of Monitoring Accuracy in Power Quality Online DevicesThe measurement accuracy of online power quality monitoring devices is the core of the power system’s “perception capability,” directly determining the safety, economy, stability, and reliability of power supply to users. Inadequate accuracy leads to misjudgment, incorrect control, and flawed decision-making—potentially causing equipment damage, economic losses, or even grid failures. Conversely, high accuracy enables precis

Electric Power Dispatching in Modern Power SystemsThe power system is a critical infrastructure of modern society, providing essential electrical energy for industrial, commercial, and residential use. As the core of power system operation and management, electric power dispatching aims to meet electricity demand while ensuring grid stability and economic efficiency.1. Basic Principles of Electric Power DispatchingThe fundamental principle of power dispatching is to balance supply and demand by

The Role of Harmonic Detection in Ensuring Power System Stability1. Importance of Harmonic DetectionHarmonic detection is a critical method for assessing the level of harmonic pollution in power systems, identifying harmonic sources, and predicting the potential impact of harmonics on the grid and connected equipment. With the widespread use of power electronics and the increasing number of nonlinear loads, harmonic pollution in power grids has become increasingly severe. Harmonics not only disr

Load Banks in Power System Testing: Applications and AdvantagesThe power system is a core infrastructure of modern society, and its stability and reliability directly affect the normal operation of industry, commerce, and daily life. To ensure efficient operation under various operating conditions, load banks—critical testing equipment—are widely used in power system testing and validation. This article explores the application scenarios and unique advantages of load banks in power system testin
