CVT Tester: Model 590K

True burden based CVT analysis done portably!!

Features include:

Ability to test for ratio errors at up to 500VA burden.
Selectable Power Factor.
Ratio error accuracy to 0.05%.
Four selectable CVT test point standards to choose from.
Tests CVT rated to 500kV with up to 3 secondary windings.
Truly portable ~ 20kg.

Please note:
This is not a simple ratio / nameplate comparison tester.

The R & D that has gone into developing this instrument is second to none.
Over 60 CVT’s from over 12 manufacturers have been carefully characterized under lab and field conditions to create a complex software
model that is able to measure a known CVT down to a 0.05% or better ratio error and even an
unknown CVT to only a 0.25% error under real load conditions.

Under test conditions the 590K takes a number of measurements and characterizes the CVT.
It then calculates the performance of the CVT under different loads and applied voltage conditions to suit
any of the four common test types used on a CVT.
If other test points are required, Red Phase Instruments is able to modify these points to suit any
regulation.

So when compared to traditional methods the 590K stands out as the only real portable alternative for
real load ratio assessment over a wide VA range and flexible Power Factor settings.

The CVT tester uses a combination of a Digital Signal Processor and a PC104 mini computer to provide
a powerful and yet easy use instrument running on a Windows XP operating system.
A large colour display on the front panel presents a large amount of easy to follow information.
