The XV Series of VLF test equipment is the latest addition to the VON family of high voltage test equipment, known worldwide as the most reliable high voltage test equipment available. Our advanced design provides you with a rugged, easy to use system that is easily portable to your test site. Digital menu based controls and an onscreen instruction system make the system easy to operate.

XV Series equipment is perfect for testing Extruded Cables (XLPR/EPR), Laminated Cables, Cable Jackets/Sheaths, Generators, Switchgear, Transformers, Insulators, Bushings, and Rotating Machines.

The VON XV Series of VLF test equipment is designed to meet all of you needs for VLF testing of underground cables. VLF has been recognized by industry as an alternative test method to the traditional high voltage DC hipot test. VLF is designed to provide similar stresses to a 50/60 Hz AC test, without the extremely high power and equipment requirements of such a test.

VLF is specified as a 0.1 Hz or slower sinusoidal wave shape. At 0.1 Hz, every cycle takes 10 seconds. The XV series will apply the voltage with a microprocessor controlled power supply, which will raise the voltage in the shape of a sinusoid in the first quarter cycle. The system will then discharge the cable with a microprocessor controlled, fully variable discharge system. At the zero crossing the system reverses polarity, and repeats the processes. Our fully variable discharge system allows us to reduce power consumption, and maintain a true sinusoid without distortion across the full range of loads.

The VON XV Series is designed to be easily portable, or permanently mounted in a vehicle. Systems can also be mounted in a vehicle in such a way as to allow them to be removed to access test sites that cannot be accessed by vehicle. Portable systems are designed in one piece with an integrated hand trucks. This allows one person to easily move the entire system over rough terrain to access the test location. The system is designed to allow easy loading and unloading from any standard truck. Runners are provided for sliding the unit into small trucks and vans, and a lifting point is provided for taller vehicles such as aerial lift trucks.
