Usage Notes
Usage Notes
Read the separate document “Operating Precautions” carefully before using the instrument. Follow
these precautions to ensure safe operation and to obtain the full benets of the various functions.
Installation
CAUTION
• Ventilation holes for heat radiation are provided on the rear of the instrument. Leave
sufcient space around the ventilation holes and install the instrument with the holes
unobstructed.
Installation of the instrument with the ventilation holes obstructed may cause a
malfunction of the instrument or a re.
• Do not place the instrument on an unstable surface or inclined place.Dropping or
knocking down the instrument could cause bodily injury or damage to the instrument.
Open 5 cm or longer
This instrument may cause interference if used in residential areas. Such use must be avoided
unless the user takes special measures to reduce electromagnetic emissions to prevent
interference to the reception of radio and television broadcasts.
Application disc
• Exercise care to keep the recorded side of discs free of dirt and scratches. When writing text on a
disc’s label, use a pen or marker with a soft tip.
• Keep discs inside a protective case and do not expose them to direct sunlight, high temperature,
or high humidity.
• Hioki is not liable for any issues your computer system experiences in the course of using this
disc.
Test lead
CAUTION
• Do not make small bends or repeatedly bend the cable.
As a benchmark, bending to 6x or less the cable diameter will damage the cable core
and cover, causing deterioration.
• Do not hold the cable when removing the clip from the workpiece.
• Hold the clip in your hand, and open and close gently.
Repeatedly opening and closing so that the clip springs risks damaging and causing
deterioration to the opening and closing mechanism.

1Overview
1.1 Overview
Windings (workpieces) found in motors, coils, and other components are
covered with insulation, but the insulation resistance may fall and short
circuits occur between proximate layers for some reason. The condition is
called a “layer short circuit”.
The ST4030, ST4030A Impedance Winding Tester not only compares and
judges waveform conformance through comparisons with existing response
waveforms, but also detects layer short circuits using judgment methods
that employ the rendering of response waveforms as numerical values (LC
and RC values). Further, incorporating the ST9000 Discharge Detection Upgrade (optional) into
the instrument enables highly precise detection of partial discharges that occur in the stages in
advance of a layer short circuit.
1.2 Features
High-speed and high-resolution sampling
Sampling using 200 MHz, 12 bit resolution enables the detection of minute changes in the response
waveform that hitherto could not be seen. In this way, it is possible to detect layer short circuits with
a high level of accuracy compared to before.
Numerical rendering of impulse response waveforms (LC and RC values)
The equivalence circuits for the impulse test are viewed as LCR linear equivalent circuits, and the
response waveforms are rendered numerically into LC and RC values. Rendering the response
waveforms into numerical values enables the response waveforms to be judged quantitatively.
Further, the data can be managed more easily than the waveform data.
Impulse can be tested with the rotor mounted
With the rotor and motor stator mounted, the stray capacitance between the rotor and the stator
changes depending on the rotor angle.
Changes in the stray capacitance also change the impulse response waveform, so judgments are
difcult using existing waveform comparison methods.
Numerical judgment values using LC and RC values can create PASS judgment area from the LC
and RC values distribution, and so by creating PASS judgment area using a healthy phase, it is
possible to test the impulse with the rotor mounted.
High-precision Discharge Detection Upgrade
Extracting the high-frequency discharge components of the response waveform enables highly
precise detection of partial discharges, which have hitherto been difcult to detect using utter
operations and Laplacian operations.
High waveform reproducibility
The applied voltage variation is small, so it is possible to detect defective products accurately.
Further, the instrument differences when the same workpiece is tested are small, so it is possible to
use the master workpiece data as is even if the instrument is replaced.
Reference: “15.5 Repeat Accuracy (Reference Value)” (p. 230)
Easy-to-use interfaces and an abundance of interfaces
The screen uses 8.4-inch color TFT crystals with touch panel for easy viewing and intuitive
operability. Compatible with various usage scenarios using external control (EXT. I/O), USB
memory, USB devices, and LAN. Further, RS-232C or GP-IB can be added as options.
