Power Quality Analyzer: Class A - MC774

Power quality analyzer is intended for detection of local power quality deviations. For this purpose it is normally positioned at the point-of-common-coupling of small and medium industrial and commercial energy consumers to:

1. monitor quality of delivered electric energy or at medium or low voltage feeders
2. detect and record possible disturbances caused by (unauthorized) operation of consumers.
   
   • High accuracy - Class A - measurements (certified by Power Standards Lab)
   • EN 50160 voltage quality evaluation with automatic report generation
   • Web-based 3-tier centralised distributed instrument data monitoring software MiSMART
   • Measurements of instantaneous values of more than 140 quantities including harmonics, flicker, power line signalling voltage, unbalance...
   • Voltage and current auto range measurements up to 1000 V RMS, 12.5 A
   • 4 voltage and 4 current channels with 32 micros sampling time
   • Serial, Ethernet and USB communication
   • MODBUS and DNP3 communication protocols
   • Support for GPS, IRIG-B and NTP real time clock synchronisation
   • Up to 20 I/0 modules (analogue in/out, pulse in/out, digital in/out, alarm/watchdog, tariff in)
   • Multilingual support
   • User-friendly setting and evaluation software, MiQen
     
     The MC774 Quality Analyser 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 MC774 is used as a part of an energy monitoring system comprising of strategically positioned meters connected to the MiSMART system software solution.
