SINCE 1986
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 6
