VLF Sinus 28

The VLF sine wave 28 kV is a small, handy and portable VLF test system for anyone who needs to test a true 0.1 Hz sine wave voltage.

The VLF test system is easy to use, thanks to its single-button operation, its clear, simply structured menu and its colour display.

Besides true sine wave AC, other waves shapes are available as positive and negative DC, square wave (load-dependent) and pulsed DC for sheath fault testing.

With a testable cable capacity of 0.7 μF at 28 kV and weighing just 25 kg, it has an excellent capacity-to-weight ratio.

If the test load is exceeded, the VLF sine wave can be automatically or manually adjusted and the frequency reduced to achieve a testable cable capacity of 5 μF at 0.01 Hz.

Test modes

• Measurement of true rms for current and voltage
• R and C load detection
• Leakage current measurement in DC modes
• Tan delta δ measurement (optional)
