HIGH VOLTAGE HVI - The World’s VLF Source Nearly 70 countries served since 1998 • Greatest Model Selection • Highest Voltages Available • Highest Power Ratings Delivered • Only VLF Thumper Produced • Rugged oil filled non-electronic design offers extreme reliability and ease of field service if ever necessary Very Low Frequency AC Hipots VLF-4022CM(F) 0 - 44 kVac peak up to 5.5 mF VLF-6022CM(F) 0 - 60-62 kVac peak up to 5.5 mF AC testing of cables and electrical apparatus is now easier than ever. Since the introduction of the High Voltage, Inc, line of portable and affordable VLF hipots, there is a practical method of AC fieldtesting various loads, particularly cables and rotating machinery, High Voltage, Inc, offers a full line of VLF AC Hipots from 28 kVac to 200 kVac with models that can test up to 50pF of load, cables over 50 miles in length and the largest of generators/motors, Use VLF for AC stress tests and/or as a voltage source for Tan Delta and Partial Discharge cable diagnostic testing, SINCE 1998, HVI has produced the most rugged and reliable VLF OUTPUT ADJUST HIGH VOLTAGE HIGH VOLTAGE -On products available. Our electro-mechanical control and our oil filled HV power supply designs are extremely dependable, and if necessary, more easily field serviced than the electronic designs of others. The HVI design has a proven 12 year track record with over 900 units in service. The HVI VLF design offers the best of everything, with manual, easy to use controls but also sophisticated data collection. Electric utilities and industrials have long recognized the benefit of our technology. HVI knows how to build long lasting field test equipment. The HVI VLF design produces a sine wave output that meets all requirements of world standards, permitting it to be used as a voltage source for VLF-6022CM - Front Panel Simple to use, manual controls. No programming necessary. Tan Delta and Partial Discharge cable diagnostic testing. Non sine wave producing VLF designs are limited in this ability and may reduce the users’ options in the future to use the VLF for diagnostic testing. Stick to the HVI sine wave producing VLF.
