ITH ALL-TEST
*A fast, easy and effective way to find broken rotor bars, eccentric rotors and casting voids. AT31 testing range is dependent upon
motor, transformer, or generator design, but the AT31 has successfully tested AC motors of hundreds of horsepower in size.
EPRI Statistics
Based on statistical data compiled by the Electric Power
Research Institute (EPRI), 47% of motor failures are due
to electrical faults/failures. The 47% can be further broken
down into rotor problems (10%) and winding problems
(37%). Mechanical faults may sometimes have root
causes that are electrical in nature.
ALL-TEST PRO® is your best choice for fault *Some testing applications will require our ALL-TEST IV PRO® or ATPRO
detection and troubleshooting. system. Contact your distributor or info@alltestpro.com for details.
HOW DOES THE ALL-TEST PRO® 31 WORK?
Phase Balance:
Looks for differences in Impedance readings between phases in ohms and %.
Fault to Ground:
Choose 500 or 1000V test. Reads to 500 Meg-ohm.
EMI:
Units are shown in mV and tells you if any electric interference is present,
which could affect your test results.
Rotor Tests:
When turning the rotor a horizontal bar is showing on the screen. This bar
extends and contracts between maximum and minimum measured values.
A fault shows up as a break in the pattern, which is easily observed.
For deeper analysis an "auto-test" is incorporated. It creates a sine-wave
as the rotor is turned and locks in to show the pattern.
