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.

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.

AC series resonance test system is a cornerstone, its import as critical as the infrastructure it supports. This article seeks to underscore the vital role of such equipment in the lifecycle of high-voltage applications. We will elucidate its indispensable applications, from the meticulous testing of power plant components to the rigorous validation of transmission lines, underscoring how the stability of our electrical supply hinges on the robustness of these systems.

There are several types of test equipment that can be applied to high-voltage circuit breakers for maintenance, troubleshooting, and performance evaluation. Some commonly used test equipment for high-voltage circuit breakers include HV Circuit Breaker Analyzers,Primary Injection Test Sets,Relay Protection Test Sets, Insulation Resistance Testers,Contact Resistance Testers,Vacuum switch vacuum degree tester, Partial Discharge Testers.

변압기 권선 변형이란 변압기 권선이 의도된 위치나 형태에서 물리적으로 뒤틀리거나 변위되는 현상을 말합니다. 이는 다양한 요인으로 인해 발생할 수 있으며, 운영상의 문제, 성능 저하, 잠재적인 변압기 고장을 초래할 수 있는데, 특히 출구 단락은 변압기에 매우 위험한 요인입니다.
