What Are the Handling Procedures After Transformer Gas (Buchholz) Protection Activation?When the transformer gas (Buchholz) protection device operates, a thorough inspection, careful analysis, and accurate judgment must be carried out immediately, followed by appropriate corrective actions.1. When the Gas Protection Alarm Signal is ActivatedUpon activation of the gas protection alarm, the transformer should be inspected immediately to determine the cause of operation. Check whether it was caused

In the field of electrical engineering, the stability and reliability of power systems are of paramount importance. With the advancement of power electronics technology, the widespread use of nonlinear loads has led to an increasingly serious problem of harmonic distortion in power systems.Definition of THDTotal Harmonic Distortion (THD) is defined as the ratio of the root mean square (RMS) value of all harmonic components to the RMS value of the fundamental component in a periodic signal. It is

When Actual Grid THD Exceeds Limits (e.g., Voltage THDv > 5%, Current THDi > 10%), It Causes Organic Damage to Equipment Across the Entire Power Chain — Transmission → Distribution → Generation → Control → Consumption. The Core Mechanisms Are Additional Losses, Resonant Overcurrent, Torque Fluctuations, and Sampling Distortion. Damage Mechanisms and Manifestations Vary Significantly by Equipment Type, as Detailed Below:1. Transmission Equipment: Overheating, Aging, and Drastically Reduced

The impact of harmonic THD errors on power systems must be analyzed from two aspects: "actual grid THD exceeding limits (excessive harmonic content)" and "THD measurement errors (inaccurate monitoring)" — the former directly damages system equipment and stability, while the latter leads to improper mitigation due to "false or missed alarms." When combined, these two factors amplify system risks. The impacts span the entire power chain — generation → transmission → distribution → consumption — af

What Is the Future of Intelligent Electrical Rooms?Intelligent electrical rooms refer to the transformation and upgrading of traditional electrical distribution rooms through the integration of emerging technologies such as the Internet of Things (IoT), big data, and cloud computing. This enables 24/7 remote online monitoring of power circuits, equipment conditions, and environmental parameters, significantly improving safety, reliability, and operational efficiency.The development trends of int

Electrical Room Inspection: Content and PrecautionsThe electrical room is a critical facility for power equipment, responsible for power supply, distribution, and energy output. Therefore, regular inspection of the electrical room is an essential task.1. Electrical Room Inspection Content: Check the operation and lock of entry/exit doors, ensure door gaps are tight, and verify the floor is level and free of obstructions. Monitor the room’s temperature, humidity, and odor to ensure environmental
