Transformer Preventive maintenance is crucial to ensure the reliable operation, extend their lifespan, and prevent unexpected failures. This involves regular inspection, testing, and servicing. Here’s a detailed overview of transformer preventive maintenance tests .

In response to the frequent occurrences of transformer short circuit accidents, we need to delve into understanding the underlying causes, examining the short circuit conditions , and strategizing to minimize their frequency and impact,checking the transformer short circuit testing.

when it comes to the utilization of 35 kV XLPE cables, the issue of abnormal partial discharge poses a significant challenge. Power outages resulting from this problem accelerate cable damage, leading to economic losses for industry development and hindering sustainable industry growth. Consequently, when analyzing partial discharge issues with 35 kV XLPE cables

VLF testing is considered more suitable for assessing the withstand capability and insulation quality of modern cables with polymer-based insulation. It provides a more realistic and less damaging test method compared to DC testing. The VLF testing method allows for a more accurate evaluation of the cable’s condition and remaining life expectancy.

Quelle est la différence entre le VLF et l'hipot ?
Le testeur VLF est un testeur de tension de tenue en courant alternatif qui effectue des essais de résistance et de diagnostic sur des objets testés à très basse fréquence, comprise entre 0,1 Hz et 0,01 Hz. Il est utilisé pour les câbles HT/MT, les moteurs, les générateurs et d'autres charges à forte capacité.

Vacuum switch vacuum degree tester utilizes an innovative excitation coil and employs the magnetron discharge method to evaluate the vacuum degree of the arc extinguishing chamber without requiring disassembly.

When the temperature of transformer accessories exceeds its allowable range for a long time, even the transformer oil temperature is 10℃ higher than normal or the temperature is still rising, the insulation of transformer will be easily damaged and broken down by high voltage,causing failure or accidents .  In order to ensure the normal work and service life-span of transformer, it is very important to evaluate the transformer heat up.  Let’s discuss the transformer testing for temperature rising in the article .

The failure of lead-acid batteries can be attributed to various factors, including vulcanization, water loss, thermal runaway, shedding of active substances, plate softening,

The heart of DC systems lies the battery, a critical component that provides emergency power during outages, supports control and protection equipment, and stabilizes power quality. To guarantee their dependability, battery test equipment are indispensable tools in the maintenance of these energy storage systems.
