The VLF sine wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables. Due to the air cooling, the VLF sine wave 34 kV can be used without interruption and is therefore ideal for all users who will be testing with 0.1 Hz sine wave voltages. The VLF testing system is easy to use, thanks to its single-button operation and clear, simply structured menu and colour display. In addition to sine wave AC, its output voltage shapes also include positive and negative DC, square wave and pulsed
DC for sheath-fault pinpointing.
