1 Transformer Testing and Protection Grounding is divided into working grounding and protective grounding. Working grounding: Grounding performed to meet the operational requirements of equipment.Protective grounding: Grounding implemented to prevent the metal enclosures of operating electrical equipment, structures of switchgear installations, and transmission towers from becoming energized, thereby endangering personal and equipment safety. Therefore, grounding of the transformer neutral point

1. Temperature Control SystemOne of the main causes of transformer failure is insulation damage, and the greatest threat to insulation comes from exceeding the allowable temperature limit of the windings. Therefore, monitoring temperature and implementing alarm systems for transformers in operation are essential. The following introduces the temperature control system using the TTC-300 as an example.1.1 Automatic Cooling FansA thermistor is pre-embedded at the hottest spot of the low-voltage win

Comparison of Domestic and International Transformer StandardsAs a core component of power systems, the performance and safety of transformers directly affect grid operation quality. The IEC 60076 series standards established by the International Electrotechnical Commission (IEC) correspond multidimensionally with China’s GB/T 1094 series standards in technical specifications. For example, regarding insulation levels, IEC specifies that power frequency withstand voltage for transformers rated at

Transformer Selection and Configuration Standards1. Importance of Transformer Selection and ConfigurationTransformers play a critical role in power systems. They adjust voltage levels to suit different requirements, enabling electricity generated at power plants to be efficiently transmitted and distributed. Improper transformer selection or configuration can lead to serious issues. For example, if the capacity is too small, the transformer may not support the connected load, causing voltage dro

Common transformer faults and their handling methods.1. Transformer OverheatingOverheating is extremely harmful to transformers. Most transformer insulation failures are caused by overheating. Rising temperature reduces the dielectric strength and mechanical strength of insulation materials. IEC 354, Loading Guide for Transformers, states that when the hottest spot temperature of a transformer reaches 140°C, bubbles will form in the oil. These bubbles can reduce insulation performance or cause f

I. Inspection of Vacuum Circuit Breakers During Normal Operation1. Inspection in Closed (ON) Position The operating mechanism should be in the closed position; The main shaft roller should be disengaged from the oil damper; The opening spring should be in a charged (stretched) energy-stored state; The length of the moving contact rod of the vacuum interrupter protruding below the guide plate should be approximately 4–5 mm; The bellows inside the vacuum interrupter should be visible (this does no

What are the difficulties in overhead line operation and maintenance?Difficulty one:Overhead lines of distribution network have wide coverage,complicatedterrain,many radiation branches and distributed power supply,resultingin "many line faults and difficulty in fault troubleshooting".Difficulty Two:Manual troubleshooting is time-consuming and laborious.Meanwhile,therunning current,voltage and switching state of the line cannot be graspedin real time,because of the lack of intelligent technical m

1.Introduction​With the increasingly stringent requirements for power supply quality in high-end facilities such as precision manufacturing, medical diagnosis, and data centers, traditional power monitoring systems, due to their low sampling accuracy and weak data analysis capabilities, can no longer meet the demand for deep insight and precise management of power quality. In response, we are introducing a new generation ​High-Precision Electrical Parameter Monitoring System. With ​millisecond-l
