Gossen-metrawatt-camille bauer, switzerland manufactures mavowatt 45, which is a multifunctional energy and power analyser, power disturbance analyser and harmonic analyser . The analyser includes three electrically isolated measuring systems with current and voltage inputs for complete measurement and presentation of all parameters in all electrical systems. The power analyser offers a high scanning rate of 50 khz per measuring system that allows tracking and detection of transients and other disturbances. The analyser is also attributed with auto scaling for different ct and pt inputs with wide measuring range of 0-3,000 amps/ 0-700 volts at frequency from 15 hz to 20 khz. The mavowatt 45 also incorporates a clear, user-friendly menu guided operation with help functions and measured data memory storage capability. This analyser is ideally suited for acquisition and evaluation of electrical quantities in power generation, distribution and transmission stations, analysis of energy consumption in various industries and applications, electrical load management for utilities, power disturbance and transient analysis in power supply systems as per relevant din/vde standards and powerful harmonic analysis as per iec 555-2 and din en50160 to prevent heat losses in machines and transducers. The powerful metra win 45 software helps to record the measured data.
