Power Quality Thailand Ltd has developed the PQSim 200D, a power quality training tool and signal generator designed to create unique signals and waveforms for testing power quality meters based on over 25 years of recorded power quality events. The tool allows users to simulate various power quality parameters, such as voltage sags and transients, useful for training new users on meter functionality. It generates continuous voltage and current signals and captures disturbances, crucial for understanding international standards and their exceptions.

3. THE PQSIM 200 D
• A 3 channel Power Quality signal generator dedicated to task of generating
the unique signals, waveforms and RMS values needed to test, demonstrate
and evaluate a Power Quality meter.
• It generates on command the power quality parameter variations. (events)
• The power quality event designs are based on 25+ years of actual power
quality events recorded at 100s of sites worldwide
• It continuously generates voltage and current signal outputs for 230v 50Hz
or 120 60 HZ or 230 V 60HZ
• The continuous waveform contains distortion typical of an inverter output.

4. POWER QUALITY TRAINING TOOL
• The task of training new users of Power Quality meters has always
been challenging.
• Power Quality generally consists of 10 basic electrical properties or
characteristics.
• Power Quality meters can record hundreds of parameters simultaneously.
• The sudden disturbance of one of these parameters is captured, recorded and
time stamped. The sensitivity settings for capturing those parameters is the
challenge.
• Defining the allowable variance in a parameter disturbance (setting the
threshold limits) requires knowledge of the International standards and
understanding of the exceptions to normal setting for specific situations.

5. POWER QUALITY PARAMETERS AT THE PUSH OF A
BUTTON
• RMS voltage variations by magnitude and duration
• Voltage sags (user selects magnitude and duration)
• Voltage notching
• Voltage swells (user selects duration)
• Voltage transients Phase to neutral
• Unipolar
• Bipolar
• Decaying ringwave
• Voltage transients Neutral to Ground
