Technical Specifications

Design & Construction

Engineered for critical high-voltage environments, the LQHVF divider features:

• Oil-Immersed HV/LV Arms - Identical dielectric media ensures temperature-stable 4000:1 ratio

• Corona-Free Top Cover - Minimizes surface discharge at extreme voltages

• Modular Assembly - Integrated basement, HV arm, LV arm, and corona shield

• Test Transformer Compatibility - Height-optimized for seamless PD measurement setups

Applications

• Partial discharge (PD) diagnostics in transformers/cables

• Dielectric strength validation per IEC 60243

• Power grid substation monitoring

• High-voltage lab calibration

• Impulse voltage testing

PD Measurement Advantage

When used as a coupling capacitor, the LQHVF achieves <5pc sensitivity="">at 1200KV - enabling early detection of insulation degradation.

Safety & Compliance

This voltage divider meets global standards for HV testing equipment:

1. IEC 60060 (High-voltage test techniques)

2. IEC 61010 (Electrical safety)

3. IEEE 4 (Standard for HV testing)

Field Safety Tip: Always verify clearance distances per IEEE 516 when deploying at full 1600KV rating.

Maintenance Guidelines

• Annual dielectric oil analysis

• Biannual ratio verification

• Storage at ≤60% humidity

• Calibration every 12 months (NIST traceable)
