Eberry Electric recently had the pleasure of welcoming customers from Central Asian countries to our production base. During the visit, our guests toured both our high-voltage circuit breaker manufacturing facility and our vacuum circuit breaker factory, gaining a close-up understanding of our advan...

In power systems, asynchronous opening and closing of disconnect switches may lead to abnormal equipment operation and affect system safety. First, the mechanical condition of the operating mechanism should be inspected to ensure proper lubrication and the absence of jamming. Next, verify that the c...

When dealing with poor contact problems in the auxiliary switch of a vacuum circuit breaker, the first step is to identify the cause of the fault. You can determine this by measuring the resistance of the auxiliary switch—if the resistance value is abnormal, it may indicate poor contact. Next, check...

Guide rail wear mainly includes issues such as surface scratches, dents, and material loss. To effectively detect these wear conditions, professional measuring tools such as hardness testers and micrometers can be used to evaluate the thickness and surface flatness of the guide rail. In addition, re...

Electronic controllers play a crucial role in modern equipment, serving primarily to achieve automatic control and management of various systems. By continuously monitoring real-time sensor data, the controller is able to analyze the operating status of the equipment and make adjustments according t...

Grounding switches play a critical role in power systems, but contact welding problems often lead to equipment failures and compromise system safety. Welding typically occurs during frequent switching operations or when the current exceeds the rated value, causing a sustained short circuit between c...

Eberry Successfully Attended the Iran International Electricity Exhibition 2025Eberry Electric proudly participated in the Iran International Electricity Exhibition 2025, marking our very first visit to Iran — and the experience was truly outstanding. The exhibition was a great success, thanks to th...

High-voltage switchgear tripping is usually associated with multiple factors. First, internal short-circuit faults are a common cause, which may result from insulation failure, equipment aging, or external interference. In such cases, it is recommended to conduct regular insulation tests to detect p...

Insulator flashover accidents typically occur during rainy weather or in humid environments, mainly due to electrical breakdown caused by surface contamination and moisture on the insulator. First, contamination layers reduce the insulating capability of the insulator surface, making it easier for c...

To effectively prevent the insulated pull rod of a vacuum circuit breaker from breaking, regular inspection and maintenance are essential. During inspections, pay close attention to the insulation material of the pull rod and check for signs of wear, aging, or degradation. Maintaining appropriate en...

Eberry Electric is proud to announce the successful application of our 110kV SF6 circuit breakers in the 110kV substation project in Samarkand, Uzbekistan.This project plays a key role in enhancing the regional power grid’s stability and supply capacity. The substation is designed to support gr...

There are multiple common factors that lead to jamming during the operation of guide rails. First, insufficient lubrication is a primary cause of increased friction. Regularly adding or replacing lubricating oil can significantly improve the guide rail’s operating condition. In addition, dirt accumu...

Oxidation of relay contacts is a common issue during the use of electronic controllers, and improper handling can affect device performance. First, regularly inspect the relay contacts for signs of oxidation. If an oxide layer is found, it should be cleaned promptly. Special cleaners and a soft clot...

Failure-to-operate faults in grounding switches usually stem from several key factors. First, mechanical faults are one of the main causes, such as wear or failure of the drive mechanism, which may prevent the switch from operating properly. Second, electrical faults should not be overlooked, includ...
