Cylinder Test Transformer HV AC Test Systems for AC Hipot Dielectric Testing¹

Product DescriptionAC Test Transformers without Partial DischargeDescriptionHVAC test systems based on cylinder modular type transformer are intended to generate a continuously variable AC test voltage at power frequency, they are the basic testing equipment for all multi-purpose HV test fields and laboratories.The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space. Rated voltage of single module can be up to 750kV, we have successfully experienced 2400kV test transformer by four modules cascaded.The test transformers are installed in an insulating cylinder shell and are oil-cooled, they are well suited for single operation and operation in series connection (cascading), so called modular type, designed for testing all types of high voltage electrical insulation, test voltage up to 2400kV. ApplicationAC voltage test systems with transformer design are used to test high voltage products (like high voltage cables, power transformers, GIS), components (bushings, arresters), and insulating materials. They can be used in a variety of applications, such as routine, type testing, in particular, wet testing, also indoor / outdoor testing, on-site testing.Some applications are:1. HV withstand tests on insulators (dry, wet, polluted)2. Applied voltage test on power transformers3. HV withstand and PD tests on GlS and GlS/GlL components4. Type and prequalification tests on cable samples5. Various HV tests on power switches and disconnectors6. HV tests on instrument transformers (CT, PT, CVT)7. Multi-purpose test system for R&D and educationFeatures1. The complete set of equipment is highly configurable, with complete voltage series, capacity series and functions;2. Compact dimensions resulting in minimum space requirements;3. High flexibility for connecting the HV lead;4. Self-developed epoxy insulation cylinder without partial discharge of system equipment is small and there is no oil leakage;5. High-quality DQ120-30 grain-oriented silicon steel sheet is adopted, and the waveform distortion rate and no-load current of products of the same kind are the smallest in China;6. Large range of application and low acoustic noise level (approx 65 to 75 dBA);7. Sophisticated protection features for optimal test object& personnel protection. Main ConfigurationsPower switch cabinetNon-partial discharge programmable variable frequency power supplyDouble-shielded isolation transformerPower supply noise filterOvervoltage electronic rapid protection deviceAdjustable compensating reactorNon-partial discharge experimental transformerProtection resistorCapacitor voltage divider and coupling capacitorPower frequency peak voltmeterComputer-controlled measurement systemPrinciple DiagramProduct Parameters1Rated voltage50 to 4×600kV2Rated current0.1 to 5A3Input voltage0.22/0.38/0.6/3/6/10kV4ControlManual & Automatic Computer controlReferenceCompany ProfileXiamen Fivestar Electric Test Equipment Co., Ltd. XIAMEN FIVESTAR ELECTRIC TEST EQUIPMENT, operating in the electricity industry, specializes in developing and providing high-voltage testing equipment, including AC Dielectric, HV DC Voltage, Impulse Voltage, Impulse current and other special tests, rating up to 2400kV AC, 2000kV DC, 7200kV Impulse.
