Description of the MAVOLOG PRO Power Quality Analyzer
The MAVOLOG PRO Advanced Power Quality Analyzer is a comprehensive device intended for permanent
monitoring of power quality from its production, transmission, distribution all the way to the final consumers,
who are most affected by inadequate voltage quality. It is mostly applicable in medium and low voltage
applications.
Lack of information regarding supplied voltage quality can lead to unexplained production problems and
malfunction or can even damage equipment being used during factory production process. Therefore, this
device can be used for the needs of electrical utilities (evaluation against standards) as well as for industrial
purposes (e.g. for monitoring the level of supplied power quality).

Purpose and use of the MAVOLOG PRO Power Quality
Analyzer
This instrument performs measurements in compliance with regulatory requested standard EN 61000-4-30 and
evaluates recorded parameters for analysis according to parameters defined in European power quality
standard EN50160. It enables storage of a wide variety of highly detailed oscillography data in 8GB of internal
flash memory based on a sophisticated trigger settings mechanism. Data can be stored in standardized PQDIF
(IEEE 1159-3) and COMTRADE (IEEE C37.111) file formats which can easily be exchanged with third party PQ
analysis SW systems.
Moreover the MAVOLOG PRO stores measurements and quality reports in internal memory for further
analysis. By accessing recorded or real time values from multiple instruments installed on different locations it
is possible to gain the overall picture of the complete systems’ behavior. This can be achieved with regard to
MAVOLOG PRO accurate internal real time clock and wide range of synchronization sources support, which
assure accurate, time-stamped measurements from dislocated units.
Stored data can then be transferred to a PC or server for post analysis. The simplest way this is done is by
directly connecting a PC with installed MAVO-View Setting Studio SW via USB cable. In cases where multiple
devices are used the MAVO-Database system server usage is recommended where all relevant data from all
system connected instruments is always available from a centralized database through the push XML
communication mechanism. To save server space high precision data can also be transferred from a selected
device on-demand using FTP.
The following characteristics are measured and recorded:

Device application and benefits
The MAVOLOG PRO Quality Analyzer can be used as a standalone PQ monitoring device for detection and
analysis of local PQ deviations, transients, alarms and periodic measurements. For this purpose it is normally
positioned at the point-of-common-coupling (PCC) of industrial and commercial energy consumers to monitor
quality of delivered electric energy or at medium or low voltage feeders to monitor, detect and record possible
disturbances caused by operation of consumers.
Identifying relevant fixed measuring points is the most important task prior to complete system installation.
The implementation of a PQ system itself will not prevent disturbances in network but rather help diagnose
their origins and effects by comparing and scrutinizing data from multiple time synchronized measurement
points.
Therefore the most extensive benefits are achieved when the MAVOLOG PRO is used as a part of a PQ
monitoring system comprising of strategically positioned meters connected to the MAVO-Database software
solution. This three-tier middleware software represents a perfect tool for utility companies, energy suppliers
and other parties on both ends of supply-demand chain. MAVO-Database data collector with “push”
communication system allows automatic recording of all predefined measured parameters in the device. All
sent data are stored in the MAVO-Database, while leaving a copy of the same parameters stored locally in
device memory of each device as a backup copy. Database records can be analyzed, searched as well as viewed
in tabelaric and graphic form using the native MAVO-Database web client application or other third-party
software. (e.g. SCADA systems, OPC server, PQ analysis established software…) At the same time device data
can also be visualized and analyzed on-demand by means of the powerful freely-downloadable MAVO-View
setting studio SW.
Server database records (with a copy in device memory) include numerous parameters of three-phase systems,
which have been setup in the device (PQ parameters, over 700 evaluated electrical quantities, I/O module
related physical parameters (e.g. temp., pressure, wind speed…). On the other hand the database also holds
data on alarms and detailed time-stamped transient, waveform, disturbance PQ data and fast trend trigger
records with complete oscillography data in standardized PQDIF/COMTRADE file formats.
