Interaction of Network and Customer Power Quality Analyser or Power Meter?Here is both!

combines the wide features ofa power quality analyser, for example long time recording, with the considerable advantages of a modern power meter: •Measurement of high voltages andcurrent in a frequency range of DC–20kHz with an accuracy of 0.1%•Exactness evaluation of powerparameters and power factors also by small cos phi•Tabulate and graphical display of themeasured data in real time•Adoption of additional analog anddigital channels to acquire the control signals and non elictrical parameters. ZES ZIMMER Power Quality Analyser PQA450 The objectives of a power qualtityanalyser are manifold. Even manifold as the choice of measuring equipment. The right choice of the equipment is the premise for a successful analysis.Often it´s not enough to measure thevoltage at the point of common coupling only but also to evaluate the interaction between the grid and the connected loads. The required parameters are not only voltage and short ciurcuit level. It is also important to analyse the load currents, power components and power factor. It is well known, that the performanceof a modern electrical appliance should be described with a high precise current measurement in a wide frequency range. This means, that the use of a high precision power meter is essential.The measurement and analysis system
