Engineered for Space-Constrained Substations

The LQHVF 300kV/100pF redefines compact high-voltage measurement with its industry-leading 1.2×1.2m footprint at 300kV rating. Designed for urban substations and confined testing environments, this solution delivers:

• Full 300kV capability in minimal space

• Ultra-low partial discharge (≤5pC @300kV)

• Scalable configuration for voltages up to 600kV

• Removable design for rapid deployment

Unmatched Space Efficiency

Occupies 40% less floor space than conventional 300kV dividers while maintaining full performance - ideal for retrofitting existing substations.

Transport & Handling

• Fits standard freight elevator (1.5×1.5m cabin)

• Components pack in 1.3m crates

• No crane required - manual handling with lift assist

Space-Constrained Applications

Urban GIS Substations

Installation in city-center gas-insulated switchgear facilities with limited floor space.

Offshore Platforms

Deployment on wind turbine converter platforms with strict weight and space limits.

Tunnel Substations

Underground railway power systems where height is constrained.

Operational Benefits

• Space Optimization: 1.44m² footprint saves valuable floor area

• Weight Reduction: 260kg enables manual repositioning

• Corona-Free Operation: Aluminum rings prevent discharge at 300kV

• Scalable: Connect two units for 600kV measurements

"The compact design allowed installation in our downtown substation without structural modifications - saving $180,000 in retrofit costs."
