Power Quality Analyzers PQA824
PQA824Power Quality Analyzer with voltage spikes (5µs) measurement Identify issues with power quality which typically manifest as dips, swells, harmonic distortion, unbalance, flicker, and transients. Power quality determines the suitability of electrical power to drive motors, machines and other end user devices. Each internal parameter is easily reached through the typical tree structure, widely known to Windows system users. The devices allow displaying the parameters in numerical and graphic mode, both for periodical analysis and for harmonic analysis. The graphic function “vector diagram” allows, among other things, to immediately evaluate the phase angle between input voltage and current signals, thus defining the loads’ nature. The 15MB internal memory allows saving recorded data for a remarkable number of consecutive days. Model PQA824, compared to PQA823 and VEGA78, also allows detecting spikes on input voltages with a minimum resolution of 5μs (200kHz), setting different trigger thresholds which are very useful when solving typical problems on installations (monitoring atmospheric charges, commutations of switching suppliers, disturbance frequencies, etc.). The Help online function available on each screen is a valid and concrete help for the operator in understanding how the devices are used.
