Ultra-Low PD EMI Suppression for High-Current 60Hz Systems

Engineered for demanding industrial power systems, the LQLVF 80kVA/2×210.5A Power Noise Filter delivers exceptional electromagnetic interference suppression with ultra-low <2pC partial discharge. Featuring dual 210.5A circuits, ONAN cooling technology, and optimized for 60Hz operation, this high-capacity solution maintains stable 0.38kV symmetric performance during 60-minute continuous full-load operation.

Technical Specifications

Performance Highlights

Ultra-Low Partial Discharge

Maintains <2pC PD level at full 0.38kV operation - exceeding IEC 60270 Class II requirements for sensitive industrial systems.

High-Current Capacity

Dual 210.5A circuits support extreme industrial loads with <1% voltage drop during continuous operation.

Optimized 60Hz Performance

Specialized design for North American 60Hz power systems with enhanced harmonic suppression.

Installation & Operation

Thermal Management

• Maintain 150mm top clearance for heat dissipation

• Maximum ambient temperature: 45°C

• Vertical mounting orientation required

Electrical Integration

1. Use 150mm² copper conductors for main connections

2. Terminal torque: 65Nm (per IEC 60947-1)

3. Ground with 35mm² cable (resistance <0.5Ω)

4. Balance load across both circuits

Commissioning Tests

• Verify PD level at 0.38kV operational voltage

• Perform 60-minute full-load thermal stability test

• Check oil level indicator before operation

Why This Filter Stands Out

• Industry-Leading Current Rating: 210.5A per circuit capacity

• Certified Continuous Operation: 60-minute full-load capability

• Ultra-Low PD Guarantee: <2pC partial discharge at operational voltage

• Specialized 60Hz Design: Optimized for North American power systems

Maintenance Protocol

1. Annual oil dielectric test (per ASTM D877)

2. Biannual thermal imaging during operation

3. PD verification every 24 months

4. 5-year comprehensive performance validation
