Very Low Frequency AC Testers
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 field-testing 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 50mF 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.
HVI offers more models and higher voltage mod-
els than any other vendor in the world. Models
range from 28kV – 200kV, offering from 0.4mF to
50mF of load capability.
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
SINCE 1998 , HVI has produced the most rugged and reliable
VLF 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 record with nearly 1100
units in service in 70 countries. 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 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.
The HVI VLF technology is protected
under U.S. Patent # 6,169,406
