The HV Diagnostics HVA30 30 kV VLF/DC Test Set is a compact, high-voltage instrument designed for very-low-frequency (VLF) and DC withstand testing of medium-voltage power cables, generators, switchgear and other high-capacity assets. Available exclusively for rent or hire, it delivers up to 30 kV RMS sinusoidal output at 0.1 Hz, making it ideal for commissioning, maintenance and fault-location support in utility, industrial and service-provider environments.
Developed by OEM H V Diagnostics, the HVA30 automatically performs VLF withstand tests and optional DC or step-voltage sequences, while continuously monitoring voltage, current and load capacitance. A single-piece, oil-free design keeps the unit lightweight and field-portable, and its intuitive keypad interface with back-lit display provides straightforward operation for technicians in challenging on-site conditions.
Key Features:
- 30 kV RMS VLF Output: Performs sinusoidal withstand tests up to 30 kV RMS (≈42 kV peak), suitable for cables rated to 25 kV class and below.
- Dual VLF & DC Modes: Switch between 0.1 Hz VLF, square-wave or ±30 kV DC for versatile insulation assessment and fault-diagnosis routines.
- Automatic Test Sequences: Pre-programmed routines simplify compliance with IEC 60502-2 and IEEE 400.2 guidelines, ensuring consistent, repeatable results.
- Integrated Measurement & Data Storage: On-board metering logs voltage, current and capacitance values for post-test reporting and analysis.
- Comprehensive Safety Systems: Built-in earth monitoring, rapid discharge and overload protection safeguard users and equipment.
- Portable, Single-Unit Design: Solid-state construction eliminates external oil resistors and reduces overall footprint for easy transport between sites.
