Advanced Features

Precision Timing Control

L-C adjustable circuit delivers microsecond-accurate delays with exceptional temperature stability

Enhanced Safety Design

Integrated corona rings reduce partial discharges by up to 40% compared to standard designs

Modular Voltage Scaling

200kV stage architecture allows flexible configuration for different test requirements

Field-Ready Portability

Compact design reduces transport volume by 30% versus conventional 1600kV systems

Typical Applications

On-site testing of power transformers (IEC 60076)
Lightning impulse withstand tests (IEC 60060-1)
Research on gas-insulated switchgear (GIS) systems
Calibration of high-voltage measurement dividers
Power transmission equipment quality verification

Performance Advantages

Wider Voltage Range: 20-100% chopping voltage scope enables more test scenarios
Improved Synchronization: <2% sync rate ensures test repeatability
Reduced Corona Loss: Patented top-ring design minimizes energy loss
Faster Setup: Portable configuration cuts installation time by 50%

Operation Guidelines

Verify all ground connections before energizing
Adjust L-C circuit for desired time-delay characteristics
Maintain minimum 2.5m clearance during 1600kV operation
Perform weekly sphere gap inspection under heavy use
Store in climate-controlled environment when not in use

Compliance Standards

This system meets or exceeds requirements of:

IEC 60060-1: High-voltage test techniques
IEEE Std 4-2013: Standard for HV testing
GB/T 16927.1-2011: Lightning impulse tests
EN 60060-2: Measurement requirements

Why This System Stands Out

The LQHCG 1600KV-400pF combines unprecedented portability for a 1600kV system with laboratory-grade precision. Its unique L-C adjustable timing circuit and optimized corona protection make it ideal for both field testing and standards laboratory applications where space constraints and measurement accuracy are equally critical.
