The HV Diagnostics HVA34 is a high-voltage testing instrument primarily used for evaluating the condition of medium-voltage cables. It’s designed to perform both Very Low Frequency (VLF) and Direct Current (DC) hipot testing, making it a versatile tool for cable diagnostics.
- VLF and DC hipot testing:Â This dual capability allows for comprehensive cable assessment.
- Compact and lightweight:Â Designed for portability and ease of use in field conditions.
- High power-to-weight ratio:Â Delivers powerful testing performance in a compact package.
- Integrated Tan Delta diagnostics (optional):Â Provides additional insights into cable insulation health.
- IEEE 400.2 compliant test sequences:Â Streamlines testing procedures.
- Sheath testing and fault location:Â Identifies and pinpoints sheath-related issues.
- Vacuum bottle testing:Â Supports testing of specific cable types.
- Cable condition assessment:Â Detects insulation defects, aging, and potential failures.
- Preventive maintenance:Â Helps identify and address issues before they lead to outages.
- Installation testing:Â Verifies the integrity of newly installed cables.
