Energomonitor 3.3T1
Energomonitor-3.3T1
Multifunctional reference instrument for measuring electrical and power quality parameters
National registry Nо: 39952-08
Calibration interval: 2 years
Аccuracy class: 0.1
Purpose
 |
Measurement and logging (including waveform capturing) of main electrical parameters in single-/ and three-phase networks, including RMS voltage and current for both sinusoidal and distorted waveforms, as well as active, reactive, and apparent power |
|
Accuracy testing, calibration and verification of single- and 3-phase active and reactive energy meters on site, monitoring of their accuracy characteristics and checking the correctness of their wiring without breaking into the circuits |
|
Testing of current and voltage instrument transformers (in the comparator mode) |
|
Measuring load power in secondary circuits of instrument transformers and electricity theft detection |
|
Measuring amplitude and peak AC voltage (at a frequency of up to 500 Hz) in one or three channels, or in a differential channel; accuracy testing and calibration of peak voltmeters |
|
Measurement and logging of power quality parameters (PQP) |
Basic specifications:
|
Operating temperature range: -20...50°C |
