3-Phase Energy and Power Disturbance Analyzer
The MAVOWATT 50 energy and power disturbance analyzer measures electrical quantities in DC systems, as well as in single and three-phase AC systems with any load. Broadband measurement is laid out for line frequencies of up to 1 kHz, and covers everything from railway power at 16 2/3 Hz to mains power with 50 or 60 Hz, right on up to onboard electrical systems with 400 Hz.
Eight isolated measuring circuits – four each for voltage and current – prevent equalizing current and allow for simultaneous measurement of phase and neutral conductor voltage and current.
By connecting a suitable measuring transducer, the fourth channel can be used alternatively for the measurement of other physical quantities, e.g. the temperature of a motor or transformer, or wind speed at a wind power turbine.
Measurements at frequency converter outputs are also possible within a broad range.
The comprehensive spectrum of functions ranges from acquisition, display and logging of mains quantities, as well as recording and analysis of energy consumption, right on up to calculation and statistical analysis of the characteristics of the voltage quality of electrical supply power in accordance with EN 50160.
In industrial applications, the precision measuring instrument is used to determine characteristic quantities of electrical consumers and generators in steady-state, as well as during dynamic processes. It also functions as a test instrument and compares harmonic current generated by electrical equipment, as well as voltage fluctuation, with specified limit values. The transient measuring function allows measurement and analysis of voltage transients of up to 1.3 kV as from a duration of 10μs.
Thanks to its compact, rugged design, the MAVOWATT 50 is not only suitable for stationary use, but rather for mobile applications as well. The integrated rechargeable battery supplies power to the measuring instrument for periods of up to several minutes in the event of power failure.
