Description

Features

  • Evaluation of the electricity supply quality in compliance with EN 50160 (only MC760)
  • Measurements of instantaneous values of more than 140 quantities (U, I, P, Q, S, PF, PA, f, φ, THD, MD,
    energy, energy cost by tariffs, etc.)
  • Harmonic analysis of phase, phase-to-phase voltages and currents up to the 63rd harmonic
  • Recording up to 64 measurands and 32 alarms in the internal memory (8 MB flash)
  • 32 adjustable alarms
  • RS 232/RS 485 communication up to 115,200 bit/s or Ethernet/USB communication
  • Up to 4 inputs or outputs (analogue, pulse, relay and watchdog outputs, digital, tariff, pulse and analogue
    inputs)

Description

Both MC760 and MC750 are intended for monitoring, measuring and recording of electrical quantities of a three-phase electric-energy distribution system. The meter is provided with 32 adjustable alarms, 8MB flash recorder (up to 64 measurands and 32 alarms), up to four input or output modules and communication. With the RS 232/RS 485 or Ethernet/USB communication the meter can be set, measurements checked and stored data downloaded. The meter functions also as an electricity meter, with the additional function of cost management by tariffs. A tariff input or a tariff clock can be set. At tariff clock setting, four periods and four work groups as well as electric energy price for each period and a work group (16 different price periods) are available. Additionally, 20 places are available for setting holidays or days when special tariff rules are valid. As an electricity meter it records energy in all four quadrants in four tariffs.

The MC760 network analyser is used for permanent analysis of electricity supply quality in compliance with EN 50160 standard. Records are stored in the internal memory for the period of the last three years. Moreover, more than 170,000 deviations of the measurands from
the standard values are stored, which enables finding eventual reasons for the problems in network. Optional limits and required quality in a monitored period can be defined for each monitored characteristic. The following characteristics are measured and recorded:

  • Frequency deviations
  • Voltage deviations
  • Voltage unbalances
  • Rapid voltage changes
  • Flicker intensity
  • Voltage dips and swells
  • Voltage interruptions
  • THD & harmonics
