Engineered for Critical HV Applications

The LQHVF capacitive voltage divider delivers laboratory-grade accuracy in field and industrial environments. Designed for 5kV systems at 50Hz, its 100:1 voltage ratio and ≤1% measurement precision make it ideal for:

• Transformer and circuit breaker dielectric testing

• Power quality monitoring in substations

• Calibration of HV instruments per IEC 60060 standards

• Research labs requiring stable voltage division

Key Technical Specifications

Advanced Structural Design

Optimized for reliability in demanding environments:

• Oil-Immersed Construction: Enhances thermal stability and prevents partial discharge

• Removable Corona Rings: Reduces surface discharge at high voltages

• Modular Components: L-arm, HV arm, and base enable easy maintenance

• Thermal Resilience: Continuous 60-min operation at 5kV; indefinite use at 3.3kV

▶︎ Field Benefit: 30% faster setup than epoxy-sealed alternatives due to modular design

Compliance & Safety Features

Meets global standards for HV measurement equipment:

• IEC 61869-11:2023 (Instrument transformers)

• IEEE 4-2013 (HV testing techniques)

• CAT III 600V safety rating

Safety Note: Integrated discharge resistors automatically de-energize capacitors after disconnection.

Operational Guidelines

1. Calibration: Perform annual calibration with NIST-traceable standards

2. Connections: Use shielded coaxial cables ≤2m to minimize noise

3. Environment: Operate at -20°C to +45°C with <85% RH

4. Maintenance: Check oil dielectric strength every 500 operating hours
