1 POWER QUALITY ANALYZER Power Measuring Instruments Solve All Your Power Quality Problems ISO14001 JQA-E-90091

2 1 Identify power anomalies simply and surely! Problems in power quality that can occur near you! Have you ever experienced these? Troubles like these are often caused by degraded electric power quality. Flickering lights Light bulbs burn out too quickly OA equipment is not working correctly Machines sometimes operate abnormally Capacitor with condenser equipment overheat 3E (overload, reversed phase, missing phase) relays are sometimes tripped Finding the cause is difficult! The quick way to handle troubles is to have a clear understanding of the cause and to determine from where problems are generated. However, it is not always possible to accurately grasp all of the phenomenon of problems error of which there can be many in the power line, even if you use recording devices or harmonic analyzing devices in your investigation of the phenomenon. You need a dedicated measuring instrument to accurately grasp these kinds of phenomenon. Fully identify the many phenomenon hiding in your power lines! There are cases in which overlooking even the smallest power trouble can lead to enormous financial loss. Checking the quality of your electric power is the best way to prevent trouble before it occurs. Transient over voltage (impulse) Occurs by lightning, contact point damage or closure of the circuit breaker or relays. Often appears as sudden voltage changes and high peak voltages. Electric power devices are damaged, particularly by high voltages or can cause reset operations in the vicinity of the origin of the cause. Voltage dip (sag) Voltage decrease over a short period of time caused by sudden large currents to the load when starting up a motor, etc. Device operation stops or a reset is caused by the drop in power voltage. Voltage swell (surge) Caused by lightning strikes or when opening or closing a heavily loaded power line causing sudden increases in voltages. Increases in power voltage can damage device power supplies and cause resets to occur. Flicker Caused by blast furnaces, arc welding or control loads for thyristors. Regular voltage impulses occur in 1 cycle or over several cycles. Phenomenon occur repeatedly over cycles so lights flicker or modulations occur in equipment. Interruption Mainly power company accidents (power supply stops due to lightning) or the instantaneous or short/long term stopping of electric power such as in the tripping of circuit breakers caused by short circuits. Recently, steps have been taken for computers, etc., with the implementation of UPS but there are still the possibilities of devices stopping or being reset due to instantaneous power outages. Harmonic Often occurs when semiconductor control devices are used in the power supplies of various equipment. Harmonics occur by the distortion of voltage or current waveforms. As harmonic distortion increases, motors and transformers can become abnormally hot or major accidents such as the damage to reactors connected to leading phase factor condensers. Unbalance Voltage and current waveform distortion, voltage decreases or reverse phase voltages occur with the increased load only on specific phases caused by devices and loads connected to each phase such as dynamic lines or the operation of unbalanced equipment. Accidents such as uneven motor revolutions, tripping of 3E breakers, overheating of transformers caused by overloads due to unbalanced voltages, reversed phase voltages and the generation of harmonic distortion. The 3196 can simultaneously measure, record AND analyze every type of phenomenon.

5 series and event measurement 4 Use event settings to capture and analyze power anomalies instantaneously Using the event setting function, a variety of power anomalies can be captured. Captured data can be retrieved simply by referring to the event list, and details (waveforms, levels, time, etc.) of the phenomena that caused the anomaly are displayed to help investigate the cause. Waveform + Time Series Monitoring Using Event Settings Independent event thresholds can be set in the 3196 for any anomaly. Captured phenomena are then stored in the event list. Detailed data such as waveforms, RMS and harmonic values related to the phenomena can then be selected from the list for display. Simple Threshold Settings for Event Triggers Trigger thresholds can be set for each measurement item Event trigger thresholds can be set while monitoring the actual input level, input waveform and harmonic graph. 1. Set while monitoring the input conditions After Measuring, Begin Analysis! 2. Display a List of Events Details of up to 100 captured events are saved automatically. The time and other information about captured events are displayed in order of occurrence. 2. Set the range of the input waveform 3. Set on the harmonic graph The category of each event is indicated, so when different events occur at the same time, any relationship becomes obvious. For detailed analysis, use the cursor to select the fault number from the event list. View the Fault Waveform in Detail! Event Setting is Finished. Start Measuring! Time series fluctuations and event data are saved in real time. Data saved includes the time each event occurred and the related captured waveforms. 1. Event Display Displays detailed conditions at the time of events, such as voltage fluctuations. The times at which each event occurred during the measurement period are apparent at a glance. Event conditions can also be viewed during measurement. Details about the selected event are displayed immediately, so analytic operations can be performed efficiently.
