6 INTRODUCING THE PQSIM 2D POWER QUALITY TRAINING TOOL AND PQ METER EVALUATION TOOL A Power Quality Thailand LTD /Power Quality Inc Product

7 THE PQSIM 2 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 s of sites worldwide It continuously generates voltage and current signal outputs for 23v Hz or 12 6 HZ or 23 V 6HZ The continuous waveform contains distortion typical of an inverter output.

8 POWER QUALITY TRAINING TOOL The task of training new users of Power Quality meters has always been challenging. Power Quality generally consists of 1 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.
