Mavowatt 45 is a multifunction energy and power analyser, power disturbance analyser and harmonic analyser, which is offered by from gossen-metrawatt-camille bauer, switzerland. Following are some of the technical features of this power disturbance analyser which include: it features three electrically isolated measuring systems with current and voltage inputs for complete measurement and presentation of all parameters in all electrical systems; . The analyser has a high scanning rate of 50 khz per measuring system that enables tracking and detection of transients and other disturbances; . It also features also auto scaling is provided for different ct and pt inputs, wide measuring range of 0-3,000 amps/ 0-700 volts at frequency from 15 hz to 20 khz. Mavowatt 45 provides some advantageous features which include: features a clear, user-friendly menu guided operation with help functions and measured data memory storage capability; . It is an ideal analyser 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 avoid heat losses in machines and transducers. The measured data can be recorded on pc with powerful metra win 45 software.
