Portable High-Voltage Measurement Solution

The LQHVF 250kV/1000pF redefines field-deployable high-voltage measurement with its unprecedented compact design and laboratory-grade accuracy. Engineered for testing teams requiring mobility without compromise, this solution delivers:

• Industry-leading partial discharge: <2pC @250kV

• Full 250kV rating in a 0.8×0.8m footprint

• Lightweight 80kg construction for rapid deployment

• Scalable configuration for voltages up to 500kV

Revolutionary Portability

At 60% smaller and 40% lighter than conventional 250kV dividers, it fits through standard doorways and deploys in 15 minutes.

Safety & Operation Protocol

1. Site Survey: Verify 3m overhead clearance

2. Assembly: Secure all corona ring connections

3. Grounding: Connect dual 25mm² cables to station grid

4. Measurement: Use shielded leads to VF source

5. Configuration: Select single or two-stage mode

6. Clearance: Maintain 3m radius during operation

7. Decommissioning: 15-minute discharge before disassembly
