Întreținerea preventivă a transformatoarelor este crucială pentru a asigura funcționarea fiabilă, a prelungi durata de viață și a preveni defecțiunile neașteptate. Aceasta implică inspecții regulate, teste și service. Iată o prezentare detaliată a testelor de întreținere preventivă a transformatoarelor. .

În răspuns la frecvența accidentelor de scurtcircuit la transformatoare, trebuie să analizăm cauzele subiacente, să examinăm condițiile de scurtcircuit și să elaborăm strategii pentru a reduce frecvența și impactul acestora, verificând testarea scurtcircuitului la transformatoare.

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.

What is the difference between VLF and hipot?
VLF Testing is a AC hipot tester that perform the withstand and diagnostic testing for test object at very low frequency 0.1 Hz to 0.01 Hz . It is applied for HV/MV cable, motor and generator and other high capacitive loads.

Testorul de gradul de vid utilizează o bobină de excitație inovatoare și folosește metoda de descărcare cu magnetron pentru a evalua gradul de vid al camerei de stingere a arcului, fără a fi necesară demontarea dispozitivului.

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.
