Main Meter and Transformer Monitoring
Track TEDAS day / peak / night bands in real time through the transformer as your electrical main meter. With a sub-meter hierarchy the double-counting risk is zero and cost allocation is correct.

When the transformer and the sub-meters are summed together, energy is counted twice and the cost figures inflate.
Which meter represents main consumption and which one sub-consumption? Allocation is impossible until the hierarchy is established.
Without separating day, peak and night consumption, tariff optimisation and budget calculations stay wrong.
If the energy data in the system is never compared with the distributor invoice, loss and theft cannot be detected.
The transformer marked as the main meter is the single source for every kWh, cost and forecast calculation.
Floor, apartment or tenant meters under the transformer are defined hierarchically and excluded from the SUM.
Hourly consumption is split into day, peak and night according to the actual TEDAS tariff bands.
External invoice kWh is compared against the system measurement; a gap above 3% raises a loss or theft warning.
Monthly kWh trend and cost split across the day, peak and night bands - a clear view for tariff optimisation.
More than one main transformer can be defined; each is tracked as a separate cost centre.
Because not every panel on site necessarily has an energy analyser, the transformer outgoing measurement is what shows the facility's true total consumption. Summing it together with sub-meters leaves a gap for the panels that have no analyser and produces an error.
Argus EMS splits hourly consumption according to the current TEDAS bands - day (06:00-17:00), peak (17:00-22:00) and night (22:00-06:00). The band hours are configurable.
Each transformer can be marked as a main meter. The total of all active main meters is used per project. A separate dashboard and cost report can be viewed for each transformer.
Yes. Sub-meters are used for tenant and apartment billing but are excluded from the total energy cost calculation. This is the most common arrangement in shopping-centre and office scenarios.
