The Miro PQ45-1k, 1000VACrms, DC powered Three Phase Power Quality Logger and Analyser is a Class A, CAT IV 600V, four voltage channel (3P + Ground + N), high precision, weatherproof (IP66) instrument that offers comprehensive power quality measurements, including Voltage Sags, Swells, Interruptions, Flicker, THD, Harmonics, Interharmonics, Temperature, Frequency, Mains Signalling, Power and Energy and Ground voltages. It is designed especially for use in renewable energy (e.g. PV, wind) where higher rated output voltages are expected, e.g. 690VAC for wind turbine generators.

Waveform and RMS captures can be generated, using various triggers, e.g. rate of change of voltage (dv/dt), sliding reference, and instantaneous voltage and current values. Alarm lists can be generated when set thresholds are exceeded.

The Miro PQ45-1k is WIFI enabled, comes with various communications protocols and optional integrated remote cellular communications.

The Miro PQ45-1k is the instrument of choice for comprehensive power quality monitoring, and is ideal for compliance reporting and energy audits for higher rated voltages, especially for the renewable energy sector, e.g. photo voltaic, wind and tidal.

Key Features

  • Certified to IEC61000-4-30, Class A
  • Compact design will allow installation in constrained spaces
  • AC and DC voltage and current measurements
  • Includes a fourth voltage channel, that can be used for e.g. measuring ground to neutral
  • Isolated voltage inputs (each channel has its own neutral) facilitate various wiring configurations
  • Two temperature channels
  • Expansion port allows for system expansion to include additional sensors, input/output controls and custom interfaces which broaden the PQ system platform. For example, interfaces include DGA, Hydrogen and Bushing monitors (Miro Auxiliary I/O Module required)
  • Suitable for all weather conditions: rugged, shock resistant, portable and weatherproof (IP66).
  • Safety rated to CAT IV 600V
    > 10kV isolation to ground
    > 10kV isolation between voltage channels
  • Detachable voltage and current leads
  • Double insulated
  • All local (WiFi) and remote communications options (3G/4G) are integrated within the enclosure – no additional peripherals required other than an external antenna.
  • GPS included as standard
  • Graphical colour display
