What parameters does a measurement unit actually measure?

Measurement parameters provided by Socomec meters:

• Voltage : RMS voltage per phase (L1, L2, L3) and average voltage. Range typically 3V-600V AC.
• Current : RMS current per phase, neutral current, average current. Measured via current transformers (CTs).
• Active power (kW) : Real power consumed per phase and total. Calculation: voltage × current × power factor.
• Reactive power (kVAr) : Inductive/capacitive power per phase. Used for power factor correction sizing.
• Apparent power (kVA) : Total power draw (combination active + reactive).
• Power factor (PF) : cos(φ) ranging 0.00–1.00 per phase and overall. Indicates efficiency of electrical system.
• Frequency : 50 Hz or 60 Hz standard AC supply frequency. Useful for stability monitoring.
• Energy consumption (kWh) : Cumulative active energy. Billable parameter for commercial installations.
• Harmonic distortion : Total harmonic distortion (THD) voltage/current, individual harmonics up to 63rd order. Critical for power quality assessment (IEC 61000-4-7).

Socomec DIRIS and POWERSYS series log all parameters at configurable intervals (15-min, hourly, daily) with timestamp. Meters certified ISO 50001 (energy management). Data retrieved via Modbus, M-Bus, Ethernet, or BACnet. Optim-elec.com specializes in energy metering solutions.
