iMC 784 Advanced Power Quality Analyzer

Power Quality Analyzer - iMC784 is a perfect solution for permanent Power Quality monitoring. Its purpose of use is:
This Class A certified PQ meter is intended for permanent Power Quality monitoring and detailed event analysis on all voltage levels Its advanced operation is usefull for network specialists to help finding problems in a network, forecasts potential problems and for future network planning
Up-to-date communication support and standard data formats enable fast integration into network or industry management systems.

In EU countries it is mandatory for utility companies to regularly report about Power Quality. Industry is also highly dependent on good Power Quality and therefore also interested in such monitoring. For that reason Power Quality monitoring has been standardised. Proper methodes are defined with IEC 61000-4-30 Ed.3 standard and sub-standards for harmonic analysis and flickers.

Applications

The MC784 can be used in power utilities (for evaluation against standards) as well as for industry purposes (monitoring supplied power quality). It 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.

Technical data

The device 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.
Apart from this, the MC784 also supports monitoring and recording of the most commonly used auxiliary sensor analogue or digital I/O data (e.g. temperature, pressure, gas/water/heat consumption, intrusion detection etc.). These readings can also be used for alarming and control purposes. The most extensive benefits are achieved when MC784 is used as a part of an energy monitoring system comprising of strategically positioned meters connected to the MiSMART system software solution.
