4. Member of the research and development team investigating “Mitigating the Effect of
Voltage Depression on Industrial Motor Control Centers Contactors”. It was derived and
considered as expansion of the study in (3). The same principles were implemented
regarding the effect of saturation of the magnetic circuit; investigations related to the
particularity of contactor sizes compared to that of motor cores were just needed. The
summary of the study is followed hereunder:
Introduction:
Electrical contactors are electromechanical devices that are identified as the weak links
in many industrial processes during supply voltage transient events. Contactors act as
ac switches in a variety of electrical systems for both power and control purposes.
Problems may occur when contactors disconnect during power disturbances. Since the
initiating events occur outside the system’s control zone, and are random; the resulting
disconnects may lead to an uncontrolled and possibly expensive process outages.
Study plan: detecting the behavior of the contactors under:
• Steady-State min. hold-on voltage.
• Point-on-the wave disengagement voltage.
Disengagement of the electrical contactors requires a combination of factors:
• Depth of the voltage sag and its duration.
• Mechanical system designed so that the electrical contacts engage before the
armature has completed its movement. As a result, the electrical contacts
engage before the magnetic circuit fully engages and the magnetic circuit
disengages partially before the electrical contacts have disengaged. This
behavior allows for a combination of conditions that will allow the magnetic
circuit to disengage and then re-engage without any disengagement of the
electrical contacts.
Test setup:
• AC contactor ABB made, rated 100 A, category AC4, supplied by 220 v, 50 Hz
from a Voltage Sag Generator.
7|P a g e

8. • Power supply connected to the contacts so as they output 24 v when fully
engaged and 0 when dropped-out.
Study Methodology:
Steady-State min. hold-on voltage study:
Conducted to establish the Steady-State Min. Hold-on Voltage keeping the contactor
engaged after it picks up completely.
The importance of this experiment is that it provides a baseline to compare contactor
performance during steady-State sags. In other words, we determine experimentally a
contactor min voltage beyond which the magnetic circuit starts to dropout.
The steady state voltage was gradually decreased until the contactor disengaged at
about 40% of nominal voltage, 88 v, which is the same ratio for all contactors having
same magnetic circuit frame and spring stiffness.
Results:
• Contactor had been found to be disengaging during sags that never drop below
the Steady-State min. hold-on voltage and that behavior might lead to the
conclusion that contactors exhibit a random disconnect behavior during sags.
This is not the truth as a steady-state study alone neglects the transient
behavior, or point-on-the wave (phase angle), and magnitude of voltage
depression (magnitude).
Point-on-the wave disengagement voltage study:
Conducted to establish the impact of Point-In-Wave (i.e. phase angle) of the initiation of
voltage sags on contactor disengagement. Data was taken to establish the minimum
voltage that would cause the magnetic circuit to disconnect as a function of point in
wave. Data was taken to determine the minimum voltage that would cause the electric
circuit to disengage was established as a function of point in wave. The sags were set for
a duration close to 20 cycles to ensure that the magnetic circuit of the contactor
achieved steady-state and the core is totally magnetized by the sagged voltage.
Data was taken where the sag occurred at 10 degrees intervals starting after the first
zero crossing.
An indication of the magnetic circuit disconnect was the clearly audible clicking of the
contactor itself as the armature re-engaged with the magnet frame. The status of the
electrical contacts was monitored by attaching a power supply to one pair of contacts.
The oscilloscope showed 5 v when the contacts were engaged and indicated 0 v when
the contacts were open.
Results:
8|P a g e

9. • The magnetic circuit first alone disengaged at voltage sags ranging from 147.4 v
to 94.6 v (67% to 43% of nominal voltage), and over points-in wave ranging
from 0 ms to 2.7 ms. Whereas the electric circuit came second, and alone
disconnected at voltages ranging from 136.4 v to 94.6 v (62% to 43% of nominal
voltage), and over points-in wave ranging from 5.2 ms to 8.5 ms depending on
the point in wave where the sag occurred. Over the range of in-wave points
ranging from 2.7 ms to 5.2 ms after the positive zero crossing, both electric and
magnetic circuits disconnected at the same voltage sag level.
• The disconnecting voltages were higher than that of the Steady-State Min.
hold-on Voltage (89 v). This could not be achieved using steady-state analysis
alone.
Conclusion and recommendations:
• The study of such phenomenon could not have achieved correct goal without
considering the combined effects of the electrical circuit and that of the
magnetic circuit.
• The division of these two circuits and subject them into study was necessary to
super-impose their mutual effect to get the conclusion.
• The voltage sags can affect contactors at values of depressed voltage values
higher than that of the minimum hold on value due to the point on wave on
which that voltage sag occurs.
• Considering the occurrence of voltage sag at the voltage zero crossing would
have a minimum effect as the magnetic circuit is highly magnetized; whereas
occurrence at or near the peak of voltage would be weakening the magnetizing
while in reversal phase, that leads to start to interrupt the magnetic circuit, and
due to the effect of the loading, a counter torque is established opposing drop-
out process. That causes the current in the contactor coil rises to high levels in
the reverse direction.
• The magnitude of the depression percent will be reflected in magnified effect
of that occurring at each point on the wave.
• The comparison of the results had shown great resemblance to those held by
other research teams considering the same point.
• Fitting a hold-on contacts to ride-through the voltage sags are not going to
eliminate voltage sags totally, it can ONLY pass some incidences.

10. • The mitigation procedure necessitates fitting a DYNAMIC VOLTAGE RESTORER
at the busses having dynamic loads such as large induction motors / dense
concentration of induction motors.
• Its feasibility study showed that ROI for this solution would be 3 years. Since
this equipment has been installed in 2009 till date, no single outage incident
has been recorded. The company savings was 500,000 $/y.
