![]() ![]() Moreover the VLF sine wave 34 kV can be upgraded to an accurate testing and diagnostic system with the optional available tan delta test attachment. Together with the optional available step-voltage probe ESG NT, sheath faults can be precisely pinpointed by using the step voltage method. 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. org/ HOMEBREW EQUIPMENT Lots of handheld equipment because its portable and can be operated in quieter more remote locations. htm NASA INSPIRE VLF-3 Receiver http: //theinspireproject. The antenna current consumption is 15 mA (early versions took 100 mA). Commercially available equipment WR-3 ELF/VLF RECEIVER http: //com/wr 3 gx 2. The high voltage switch unit is maintenance-free and fully safe to touch. The system is controlled with the MGS semi-automatic control unit. A base unit allows 12V power to be fed up the coaxial cable feeder to the antenna. The transcable 4000/S 32-3 cable test van is a 32 kV cable fault location system in 3-phase version. The VLF testing system is easy to use, thanks to its single-button operation and clear, simply structured menu and colour display. The antenna is a short vertical dipole antenna 1.8m (70') high with a built-in low noise high dynamic range RF amplifier. Due to the air cooling, the VLF sine wave 34 kV can be used without any interruption and is therefore ideal for all users who will be testing with 0.1 Hz sine wave voltages. ![]() battery technology to maintain a man-portable power supply for a year of. The VLF sine wave 34 kV is a compact, robust and portable VLF sine wave test system for medium voltage cables. A second ELF/VLF receiver architecture, the VLF Advanced Technology plat. ![]()
