Performance Advantages

1. Ultra-Low Impedance Design

• <1.5% short-circuit impedance enables superior voltage regulation - 5× better than standard test transformers

• Minimal voltage drop during load fluctuations

2. Resonant Testing Optimized

• Ideal for variable-frequency resonant test systems (VFRS)

• Enables energy-efficient testing of:

• XLPE cables up to 500kV class

• Gas-insulated substations (GIS)

• Large power transformers

3. High-Power Density

• 1600kVA capacity in single-unit design reduces test bay footprint

• 400kV/4A output enables direct testing of utility-scale equipment

Typical Applications

• Cable Manufacturers:
  Type testing of 500kV+ transmission cables per IEC 60840

• Utility Test Labs:
  Power transformer induced voltage tests (IEEE C57.12.90)

• GIS Producers:
  Lightning impulse tests for 420kV switchgear

• Research Institutions:
  HVDC component development

Technical Validation

*"Engineered for ISO 17025-accredited facilities requiring 1600kVA+ testing capacity. With revolutionary <1.5% impedance and dual-winding design, this system delivers 92%+ energy efficiency in resonant configurations - reducing operational costs by up to 40% versus conventional test methods."*
