HFRS 400kV/800kVA Dual-Mode Resonant System

Designed for flexible high-voltage testing, the HFRS 400kV/800kVA system offers dual-configuration operation with laboratory-grade <10pC partial discharge performance in field conditions.

Dual-Configuration Performance

1. Series Connection (400kV Mode)

• Output: 400kV at 2A (800kVA)

• Inductance: 636H ultra-high precision

• Withstand: 440kV for 1 minute

2. Single Module (200kV Mode)

• Output: 200kV at 2A (400kVA)

• Inductance: 318H precision winding

• Withstand: 220kV for 1 minute

Precision Engineering

Core Technical Parameters

Advanced PD Control System

Discharge Prevention Technology

• Triple-shielded winding design

• Corona-free bushing termination

• Vacuum-processed transformer oil

Thermal Management

• Iron-shell oil tanks provide:

• 35% better cooling than epoxy

• Integrated cooling fins

• Dual breather capsules:

• Pressure regulation

• Moisture indication

Field Deployment Features

Transport Protection

• Vibration-tested per IEC 61373 for:

• 1500km railway transport

• 800km highway movement

• 400kV-rated lifting system:

• Load limit sensors

• Anti-sway locks

Certification & Compliance

• Partial discharge: IEC 60270 Class I

• Insulation: IEC 60060-1

• Transport: IEC 61373 Category 1

Why This System Stands Out

1. Dual-Voltage Operation: 200kV or 400kV testing

2. Research-Grade PD: <10pC measurement capability

3. Field Reliability: Maintains specs after transport
