Unmatched Capacity for High-Current Testing

The LQHVF 265kV/15000pF sets the new benchmark in high-capacity voltage measurement with its extraordinary 15nF capacitance - the highest available for commercial 265kV systems. Engineered for the most demanding test scenarios, this solution delivers:

• Massive 15nF capacitance for currents up to 7.5A at 50Hz

• Enhanced 291.5kV/1min insulation withstand (110% rated)

• Broad 20-300Hz frequency coverage for resonant systems

• Scalable architecture for voltages up to 530kV

Ultimate Current Handling

With 15000pF capacitance at 265kV, handles measurement currents up to 44.1A at 300Hz - enabling testing of ultra-long cables and large power transformers without external compensation.
