Capture all power anomalies without fail!  
Problems with power quality are all around us  
Have you ever experienced any of the following ?  
Discovering the cause can be difficult  
The quickest way to solve power problems is to have a clear  
understanding of the cause, and be able to determine where the  
phenomenon occurred. However, it is not always possible to  
accurately grasp all of the various types of anomalies that may  
occur on power lines, even when using recording or harmonic  
analysis devices to investigate them.  
• Flickering lights  
• Light bulbs burn out quickly  
• Electronic office equipment does not function properly  
• Sometimes devices operate abnormally  
• Overheating in facilities using condensers fitted with  
reactors  
• 3E (electrical overload, reverse phase, or phase loss) relays  
sometimes trip  
These types of problems and others are often due to degraded power quality.  
Dedicated measuring instruments are required in  
order to accurately grasp these kinds of anomalies.  
Fully identify the many phenomena hiding in your power lines  
Instantaneous interruptions  
Phenomenon :  
An instantaneous or short/long term power  
supply interruption caused by accidents at the  
power company (such as interruption of power  
transmission due to lightning strike) or tripping  
of breakers due a power supply short.  
Overlooking the smallest of power anomalies  
can lead to enormous financial loss. Checking  
the quality of your power lines is the best way to  
prevent problems before they occur.  
Transient Overvoltage (Impulse)  
Phenomenon :  
Occurs due to lightning or circuit breaker/relay  
contact damage or closure. Often involves  
radical changes in voltage with high voltage  
peaks.  
Damage :  
Thanks to the increasingly widespread  
adoption of uninterruptible power supplies, equipment such as computers  
is increasingly protected against this problem. However, it may still cause  
other devices to stop operating or reset.  
Damage :  
In the vicinity of the event, high voltage often  
damages equipment power supplies or causes  
devices to reset.  
Harmonics  
Phenomenon :  
Often occurs due to voltage/current waveform  
distortion when a semiconductor control device  
is used in a device's power supply.  
Voltage Dip  
Damage :  
Phenomenon :  
When harmonic components become too  
Caused by momentary voltage drops resulting  
from large rush current in loads, such as when  
starting up a motor.  
large, they can cause serious malfunctions, such as overheating in motor  
transformers, or burn-out of reactors connected to phase advance capacitors.  
Damage :  
The drop in voltage may cause devices to stop  
operating or reset.  
Unbalance factor  
Phenomenon :  
Voltage/current waveform distortion and voltage drops  
or voltage phase reversals can occur when the load  
on a particular power line phase increases due to load  
fluctuations or imbalances.  
Voltage Swell  
Phenomenon :  
Caused by lightning strikes or opening/closing  
power lines with heavy loads, causing the  
voltage to swell momentarily.  
Damage :  
Voltage imbalance, reverse phase voltage, and  
harmonics can result in events such as uneven motor  
rotation, tripping of 3E breakers, and overheating due  
to transformer overloading.  
Damage :  
The surge in voltage may damage equipment  
power supplies or cause devices to reset.  
Flicker (IEC, ∆V10)  
The 3196 can  
Phenomenon :  
Caused by blast furnaces, arc welding, and  
thyristor-controlled loads, and involving  
regularly repeated voltage impulses spanning  
one or more cycles.  
simultaneously  
measure, record, and  
analyze all of the above  
phenomena.  
Damage :  
Because this phenomenon is cyclically repeated, it may cause lights to  
flicker or devices to malfunction.
