HCRS 1500kV/9000kVA Modular Resonant Test System

System Configuration Matrix

Key Performance Parameters

• Partial Discharge: <10pC @1500kV, <2pC @1050kV

• Waveform Distortion: ≤1.5% THD

• Quality Factor: Q≥50 (standard), Q>40 (worst-case)

• Noise Level: ≤70dB @5m distance

• Insulation Withstand: 1650kV (110% rated) for 1min

Advanced Protection System

1. Triple-layer protection: Over-voltage/current + flashover + air gap limit

2. Automatic return-to-zero mechanism for air gap adjustment

3. Phase sequence detection with motor reversal protection

4. Real-time air gap monitoring via control console

5. Synchronized transmission across modules (±5% impedance matching)

Structural Innovations

Core Components

• Magnetic Core: 30-0-130 grain-oriented steel with chip removal treatment

• Noise Control: Curing agent integrated core assembly (≤70dB)

• Cooling System: ONAN cooling with thermal expansion compensation

Modular Design Features

• Quick-connect transmission shafts with backup protection

• Standardized HV lead wire interfaces

Operational Guidelines

Quality Assurance

This system implements:

• Impedance matching test (±5% deviation requirement)

• 72-hour burn-in test before shipment

• Partial discharge calibration with 100pC reference

• Third-party certification available (ASTA, KEMA, etc.)

Pro Tip: The system's wide inductance adjustment range (24.66-25356H) allows testing of various equipment from power transformers (typically 10-100nF) to long cables (0.1-1μF) with single setup.
