Energomonitor-3.3T1-C

Portable precision comparator

ACCURACY CLASSES: 0.1

NATIONAL REGISTRY N: 39952-08

DESCRIPTION:

The multi-functional Energomonitor 3.3T1-C can be utilized as a reference meter, a CT/VT test comparator, circuit inspections, accuracy and calibration testing, and for amplitude and peak AC voltage measurements.

  • 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
  • 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
