Triggered Trace Memory

7.4.1

Description

The Triggered Trace Memory can be used to detect and record system disturbances. The 
PQMII uses a dedicated continuous sampling rate of 16 samples per cycle to record 
fluctuations in voltage or current as per user defined levels. The PQMII calculates the true 
RMS value of one consecutive cycle, or 16 samples, and compares this value with the user-
defined trigger levels to determine if it will record all sampled waveforms. The sampled 
waveforms include Ia, Ib, Ic, In, Va, Vb and Vc.

Since the PQMII requires a minimum 20 V for detection and has an upper voltage input 
limit of 600 V, the following limitation exists for the Trace Memory undervoltage and 
overvoltage trigger levels:
