High Voltage VLF Test Equipment |
|
Very Low Frequency (VLF) testing is internationally accepted as a safe and effective method for testing high voltage equipment. VLF test techniques are popular with cable testers but the concepts are spreading rapidly to other domains where similar benefits are evident.
The HVA power pack products are the smallest, lightest, most compact and most advanced universal high voltage range of VLF test instruments available. These HVA’s have the highest power to weight ratio of any comparable unit available and are available in a wide range of voltage and power outputs.
BENEFITS:
- Safe testing - cable is discharged on every cycle
- Alternating field less likely to polarize or damage the cable and tests both the resistive and reactive components of the dielectric
- Dielectric responses at VLF track those at system frequencies
- Pure sinusoid waveforms enable diagnostic testing
- Portable and cost effective
FEATURES:
- Single box resulting in minimal interconnections
- Air cooled
- Multiple voltage waveforms: Sinewave, Squarewave, DC and ramped DC
- Different models for different voltage/power applications
- Integrated measurement of the applied test voltage, current, capacitance, resistance and time are displayed and recorded
- Automatic or manual modes of operation
- Automatic calculation of the optimum frequency for larger loads
- Breakdown detection with auto stop or burn-in fault conditioning mode
- Software included for test design and test reporting
- Built in discharge resistors and many safety features
- Independent and easy operation – no pc required
- Onboard memory for test sequences and results
- Reliable performance
- Rugged construction
- European design and manufacture
- Built-in safety features
