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.

มีอุปกรณ์ทดสอบหลายประเภทที่สามารถนำไปใช้กับเบรกเกอร์แรงสูงได้ เพื่อการบำรุงรักษา การแก้ไขปัญหา และการประเมินประสิทธิภาพ อุปกรณ์ทดสอบที่ใช้กันทั่วไปสำหรับเบรกเกอร์แรงสูง ได้แก่ เครื่องวิเคราะห์เบรกเกอร์แรงสูง (HV Circuit Breaker Analyzers), ชุดทดสอบการฉีดกระแสหลัก (Primary Injection Test Sets), ชุดทดสอบระบบป้องกันรีเลย์ (Relay Protection Test Sets), เครื่องวัดความต้านทานฉนวน (Insulation Resistance Testers), เครื่องวัดความต้านทานจุดสัมผัส (Contact Resistance Testers), เครื่องวัดระดับสุญญากาศของสวิตช์สุญญากาศ (Vacuum Switch Vacuum Degree Tester), และเครื่องวัดการคายประจุส่วน (Partial Discharge Testers).

Transformer winding deformation refers to the physical distortion or displacement of the transformer windings from their intended position or shape. It can occur due to various factors and may result in operational issues, reduced performance, and potential transformer failures,with outlet short-circuits being particularly hazardous to transformers.
