Monitor Your Facility with Energy Analyzers
Connect the energy analyzers already in your panels to Argus EMS over Modbus TCP/RTU and gather power, energy, reactive and harmonic readings on one screen. No device replacement needed.
What Does an Energy Analyzer Do?
An energy analyzer is a panel-mounted device that measures voltage, current, active/reactive power, energy indices and harmonics. Argus EMS reads Schneider, Siemens and ABB analyzers over Modbus TCP/RTU using a ready register template. The readings feed consumption monitoring, EPDK reactive-penalty tracking, subtenant billing and budget forecasting — nobody has to walk to the panel and read the display.
What the Analyzer Measures, What Argus Does
Voltage and Current
Phase-neutral / phase-phase voltage, phase currents and neutral current. Argus derives phase imbalance from these values and points to the panel where one phase is overloaded.
Active and Reactive Power
kW, kVAr, kVA and power factor. Live values appear on the dashboard; 15-minute averages feed trend charts and peak analysis.
Energy Indices
Cumulative kWh and kVArh indices. Consumption is always derived from the index delta (MAX − MIN), so billing stays consistent even if a meter is reset.
Harmonics (THD)
Total harmonic distortion of current and voltage. High THD means extra heat loss in the transformer and neutral overloading; the need for a filter becomes objectively visible.
Four Steps from Analyzer to Dashboard
Select the Model
The analyzer model is picked from the template library, arriving with its register map, scaling factors and data types. For a model not on the list, the register map is defined once.
Connect
An analyzer with an Ethernet port is read directly over Modbus TCP (port 502); an RS-485 analyzer is read through a Modbus gateway. Slave ID and baud rate are entered from the interface.
Collect Data
The field agent reads the registers every 15 minutes, writes them to a local queue and forwards them to the server over an encrypted link. If the line drops, data is kept for 30 days and sent automatically once the connection returns.
Monitor and Alarm
Readings turn into trend, comparison and cost charts on the dashboard. Threshold breaches, approaching reactive limits and communication loss raise alarms automatically.
What the Analyzer Reading Is Worth
On its own an energy analyzer only shows an instantaneous value; someone has to walk to the panel and look at the display. The measurement becomes valuable when it is recorded continuously and compared over time: which shift consumes more, which line runs idle at night, will the reactive ratio cross the penalty limit by month end.
Argus EMS turns analyzer data into a structure that answers those questions. Main meter and transformer readings give the facility total, sub-analyzers give the floor/tenant/line breakdown, and the gap between total and breakdown reveals common-area consumption.
- Consumption breakdown by facility and floor
- EPDK reactive penalty limit tracking
- Subtenant energy billing
- Peak hour and maximum demand analysis
- Phase imbalance and THD detection
- Monthly budget forecasting and variance
