Megger VLF Sine Wave 34 kV | PORTABLE VLF SINE WAVE TEST SYSTEM
The VLF sine wave 34 kV is a multi-purpose device: it can be used for cable testing, sheath testing, and in combination with the optional step voltage probe ESG NT2, for sheath fault pinpointing.
- High test capacity of 5 µF
- Suitable for outdoor use (IP 54)
- Single-button operation
- Integrated safety system
- Reporting
- Continuous duty cycle
The VLF sine wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables.
The design, optimized for rapid transportation and quick setup, and the continuous duty cycle are two attributes that qualify the system
as an ideal tool for routine cable testing. For both 0.1 Hz sine wave voltage tests and rectangular or DC voltage tests, the VLF sine wave 34 kV fills the highest demands on the test voltage quality and stability. Moreover, the integrated "breakdown detection" shuts down the test voltage in the event of an excessive charge current and guarantees limited damage to the cable.
Consistent single-button operation combined with a sophisticated operating concept allows a fast and targeted use of the system.
