Multi-functions meters for Low Voltage and High Voltage applications

Multi-functions meters for measuring electrical parameters for single & three phase low and high voltage networks.

Introduction

Multi-function meter measures the extent of electrical values for all LV or LV/HV networks. It allows starting from the front panel to configure and display all the electric parameters and to exploit the functions of measurement, metering and energies management,harmonics analysis, remote control and control state of control devices, communication and detection of high voltages,peaks and voltage disconnections. This device is a multi-function meter for measuring electrical values for single, two and three phase low and high voltage networks.

SM102E

Measurement in real effective values (TRMS) of:
  • current per phase and neutral in instant and maximum value
  • phase-to-neutral and phase-tophase voltages, In instant
  • frequency, In instant
  • active positive power total in instant and maximum value
  • reactive positive power total in instant and maximum value
  • apparent positive power total in instant and maximum value
  • power factor (PF) total with inductive or capacitive indication
  • harmonic distortion rate (THD) up to 51 on phase-to-neutral and phase-to-phase voltages and currents (THD 3U, THD 3V, THD 3I)
Energies meters
  • positive active energy meter
  • positive reactive energy meter
  • programmable hour run meter

SM103E

  • Same measures as for SM102E with average values

  • harmonic distortion rate (THD) up to 51 on phase-to-neutral and phase-to-phase voltages and currents (THD 3U, THD 3V, THD 3I, THD In)
Metering:
  • active and reactive power meter on 4 quadrants
  • apparent power meter
  • programmable hour run meter
