POWER QUALITY ANAL YZERS PQA series and VEGA78 can record all parameters of voltage, current and power simultaneously in order to achieve an advanced mains monitoring as well as a full analysis of spikes and ickers in a simple and intuitive way. ®

Any company can be subject to a reduction in power quality or to an increase in management costs due to inner or external causes so bringing about damages to electrical equipment. PQA series represents a prompt solution to meet engineers’ requirements in every electrical eld, as regards monitoring single- and three-phase networks with the aim of detecting and solving any problem in power supply systems. Disturbances are featured by one origin (or more than one) and by a series of events transferred to the users. The noise origin is not always or exclusively due to the mains supplier, more often...

Instrument configuration Analyzer setting Before starting a recording the instrument shows a series of system configurations: 4-wire, 3-wire, single, ARON so giving the user the opportunity to define clamp meter type STD or FLEX, clamp's full scale, system frequency as well as interface with voltage transformers (TV) of the installation under test displaying the value of voltages on the primary side of the transformers themselves. Recorder setting Under this section the instrument permits the user to define any detail for activation of recordings, selection of parameters, type of analysis to...

Statistical analysis Inrush currents During a dynamic phase such as the start of motors as well as of uninterruptible power supplies or other applications, measurement of inrush currents aims at properly sizing the installation in order to estimate how other elements such as RCDs and fuses could be affected. PQA models are capable of carrying out recordings of inrush currents with minimum resolution of 10ms whose data can be reported both - The number of detected events event occurrence - Date/Time when event took place - Maximum value of inrush current. Graphs show TRMS values of quantities...

TopView software TopView software is a multifunctio- nal application program capable of managing results measured by sa- fety testers, power quality analyzers As for power quality analyzers permits the following operations: - Instrument setting (system type, - On line display of quantities mea- sured by the instrument (numeri- cal values, waveforms, histograms, saving of instantaneous samplings) - Data transfer from instrument to PC through USB and accurate data analysis with graphs and tables - Creation of professional reports on power quality according to Differential analysis of energy Creation...
