ANSWERS
General Questions:
a What is the test range of
ALL-TEST Pro™ equipment?
Both the ALL-TEST PRO™ 31and ALL-TEST IV
PRO 2000™ have been successfully used on equipment from fractional
through 10’s of thousands of horsepower. Our technology allows
us to test windings regardless of physical size, power and voltage rating.
Tests can be performed at the motor, motor control center or disconnect
from a few to hundreds of feet distant.
a What type of equipment can
the ALL-TEST IV PRO 2000™ test?
The ALL-TEST IV PRO 2000™ is designed to test AC/DC electric motors,
including synchronous and wound-rotor motors; AC/DC traction motors
including locomotive and hybrid vehicle motors; Control coils and transformers;Transmission
and Distribution transformers; Machine tool motors; Servo motors; and
virtually any type of coil-wound device of any size, power and voltage.
a Can ALL-TEST Pro™ instruments
and software predict the condition of the equipment and recommend corrective
actions?
ALL-TEST Pro™ instruments are designed to collect basic de-energized
electrical information which can be immediately reviewed by the user.
With simple rules, the user can quickly evaluate the condition of the
motor without having to understand the type of information or how a
motor works. This information can also be entered or uploaded into ALL-TEST Pro™ software programs, such as the TREND 2003 or EMCAT, which
will provide you with detailed results and allow you to trend results
over time.
a Do I have to perform a rotor
test if I see a phase unbalance with the ALL-TEST IV PRO 2000™?
Absolutely not. The ALL-TEST IV PRO 2000™ is the only instrument
of its type to present both inductance and impedance readings. Therefore,
if you see a phase unbalance in inductance, you can immediately compare
it to impedance. This method is used to determine if an unbalance is
due to winding contamination or overheated windings. Evaluation can
be done in a glance or via software. Other inductive-based instruments
require a 20 – 30 minute rotor test to determine the cause of the
phase unbalance and usually leave the user unclear as to the results.
Rotor faults account for less than 5% of motor failures (EASA, 2001),
which is down from 10% (EPRI, mid-1980’s). Normally, a rotor test
is only performed during troubleshooting as it requires movement of
the shaft.
a Can the ALL-TEST PRO™ OL test motors greater than 600 Volts?
Yes. However, the standard test fixtures are rated for 600 Volts,
so you have to use the motor’s CT’s and PT’s when
testing above 600 Volts. Special order test fixtures are available for
high voltage applications.
a
Can the ALL-TEST PRO™ OL test DC Motors?
Absolutely. ALL-TEST Pro™ has extensive experience testing DC motors
both energized and de-energized. The ALL-TEST PRO™ OL even allows the
technician to troubleshoot the DC Drive’s operation. All can be
done with one less than 1 minute reading.
a Can
the ALL-TEST PRO™ OL test Generators?
Both AC (Alternators) and DC (Generators) can be tested with the ALL-TEST
PRO™ OL. The instrument provides unique data for analysis which allows
it to be the ONLY electrical signature analyzer, or motor current signature
analyzer, on the market that can test a generator online.
a Can
the ALL-TEST PRO OL test Variable Frequency Drive applications?
Absolutely. ALL-TEST Pro has extensive experience testing both the motor
and VFD in variable frequency drive applications. Just as with DC applications,
the ALL-TEST PRO OL even allows the technician to troubleshoot the VFD’s
operation. All of this is done with a simple 1 minute reading.
a How
long does it take to apply ALL-TEST Pro Motor Circuit Analysis and Electrical
Signature Analysis technologies?
All of the ALL-TEST Pro™ instruments provide step-by-step menus for the
operator along with simple data interpretation rules. The ALL-TEST Pro™ software for both MCA and ESA technologies provide automated analysis
of the electric motor and related systems. In effect, most ALL-TEST
Pro™ technologies are put into use with only a few hours of self training
with expanded capabilities that come with experience, technical support
and our onsite or off site training programs.
SOFTWARE - EMCAT
a I have installed the software
and security key, but on startup the EMCAT software is telling me that
I do not have a software key.
Keep the key installed in the parallel port, but close EMCAT. Open your
EMCAT CD ROM and go to the ‘Send User’ directory. Double-click
on the ‘install.exe’ file and follow the instructions that
show on the screen. You can then start EMCAT.
a I am getting security errors
during installation.
EMCAT registers components into your computer. This error occurs when
you are attempting to install onto a system without administrator rights.
Have your administrator install the software onto your system. (Normally
occurs with Windows NT or 2000).
a I am getting Runtime errors
when operating EMCAT.
This is a Windows issue. This often occurs when there are older versions
of dynamic linking files (.dll’s) or older versions of Microsoft
Office present on the machine. These are normally fixed by downloading
the latest Microsoft Service Pack from www.microsoft.com for your operating
system or Microsoft Office. Usually occurs when operating Office 95
or Windows 98.
