Energomonitor 3.3T1

Portable three-phase reference standard meter, comparator and power data logger in one instrument.

ACCURACY CLASSES: 0.1

NATIONAL REGISTRY N: 39952-08

DESCRIPTION:

Field of application:

As a power data logger: measurement and logging of

  • Electrical power/energy parameters (RMS of current and voltage for both sine and distorted waveforms, phase angles, active, reactive, apparent power, PF etc.)
  • Basic power quality parameters (harmonic measurements, voltage and frequency deviation, unbalance indicators etc.)

As a reference meter:

  • on-site performance, accuracy and calibration tests of single- and three-phase electric energy meters (active or reactive energy); control of correct meter wiring (without breaking into the circuits)

As a CT/VT test comparator:

  • on-site performance, accuracy and calibration tests of current and voltage instrument transformers
  • Inspection of secondary circuits of instrument transformers (load power measurements), e.g. within automatic metering and billing systems
  • On-site performance, accuracy and calibration testing of instrument transducers of current, voltage, active and reactive power

As a reference peak voltmeter:

  • Amplitude and peak AC voltage measurements (up to 500 Hz) across one/three channels and one differential channel; accuracy testing and calibration of peak voltmeters

Basic specifications:

  • Voltage measurement range: 0.6...360 V
  • Nominal current: IN =0.1, 1, 0.5, 5, 10, 50, 100, 300, 500, 1000, 3000 А
  • Operating temperature: 20...50°C
  • Weight: 2 kg

Accessories:

  • Rechargeable Power Supply with Battery Charger + Power Adapter
  • Current Clamp Switch Module
  • Photoelectric Scanning Heads
  • Pulse Former (PF)
  • Current Transformer Calibration Switch CTCS-3.3
  • Transformer Burden Measuring Device (TMBD)
  • Current Transformer Block (for direct measurements of current)
  • Current clamps
  • Voltage Test leads
  • Package

Note! We offer various training programmes for users of Mars-Energo instruments and software.
