INTRODUCING THE PQSIM 200D POWER QUALITY TRAINING TOOL AND PQ METER EVALUATION TOOL
A Power Quality Thailand LTD /Power Quality Inc Product
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.
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.
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
As generated by PQSIM 200 and recorded on a Dranetz PX-5 10
