Power quality analysers are used to measure electric power signals ensuring the measurement of the electrical signal, monitoring the operation of the electrical power system is working within that power. This is important as electrical equipment will not work to capacity or malfunction without the right electrical power. RS Components work with major electrical test and power measurement equipment manufacturers, including Fluke, Chauvin Arnoux, Keysight, including the RS PRO brand, all recognised for their expertise in delivering performance within the industry. Our range includes calibrated power quality analysers with full calibration RSCAL certification.Power quality analysers are multi-function instruments that measure and test various electrical signals such as direct current, alternating current, AC-voltage, DC-voltage, harmonics and much more depending on the model. The data can then be logged and analysed with the software supplied with the power quality analyser helping you to avoid costly problems such as:Electrical equipment resets.Data errors.Equipment failure.Circuit board failures.Power quality supply issues.Software corruption.Electrical system overheating.Our range of power quality analysers will not only assist in monitoring energy performance and minimise the risks of electrical equipment damage and failure but are available in every format to suits your needs.Types of Power Quality Analysers (PQA) Available.Portable, handheld, desktop.Mains power or battery operated.Calibrated (with certification).Measurement standards.Various interface options (ethernet, LAN, USB, RS232, GPIB).Display Types.Backlit, LCD, Colour, Graphics, TFT.Measurement Types.AC Current, voltage, wattage.Current, energy, flicker, frequency.Harmonic, impedance, inrush, inverter efficiency.
