Now we have two types of test transformer: YD-Relative humidity of HV component(Non condensing) Voltage 5kV ～ 500kV/Capacity 5kVA ～ 1000kVA YDT-Series modular type(epoxy barrel) test transformer Voltage 10kV ～ 1500kV/capacity 1.0kVA ～ 1500kVA

Comparison of IGBT Power Source with MG unit: Transformer complex test  main equipment:

• Detect enameled wire conductor resistance and resistivity • To set two kinds of materials and to meet market demand. • The results will appear on LCD touch screen. According to the sample resistance to select gear. • All test data and spool product information can be automatically transmitted to the top position machine and automatically saved and analyzed by QME enameled wire quality management system.

The PD detector is mainly used for power transformer, HV CT/PT, arrester, HV switch, HV XLPE cables, etc.The test is based on apparent charge measuring description as per IEC 270. The calibrated charge is generated from input impulse of 100pF capacitor. 10mV step voltage means 1pC partial discharge and the rising time of step voltage is less than 50ns.

• Execution standard：GB/T4074.5-2008 • It is a prompt, simple and convenient tester applied to test pinholes of enameled wires. • It is applied to all enameled wires without limitation of the wire diameter or specification. It operates simply. • Its testing results are direct, stable and reliable.

• It is applied to test metal wire whose stretch breaking force is not more than 3000N • Test finishes automatically, user input the diameter of the sample, it can figure out its tensile strength automatically • It can connect with computer and display ten sample’s curves in different color, with percentage elongation (%) as x-axis and pull force (N) as y-axis. Every average test result of sample can be figure out when the sample are less than 10
