 # Use Case
 
-Virtual Meter integrated in a **host** device on a dedicated (for example: an EV charger, a battery, a heatpump...) or shared (for example: plugin battery or heater) circuit

 # Test Setup
 
-* **Grid Setup:** Single-phase electrical system, behind an isolating transformer, TN earthing with neutral-earth bond at transformer terminals
+* **Grid Setup:** Single-phase or Three-phase electrical system, TN earthing with neutral-earth bond at grid connection point
 * **Reference Meter:** [Shelly 3EM](shelly-3EM-datasheet.pdf), using split core CTs, class B with ~1% accuracy
-* **Calibration:** Calibration was performed manually, mapping the voltage drop to the reference power, to set the scaling factor for the virtual meter.

+* **Calibration:** Calibration was performed manually, mapping the voltage drop to the reference power, to set the scaling factor for the virtual meter.
+* **Loads:** Common household loads (mix of resistive, inductive and capacitive) activated for 10-20 sec (hotplate, oven, dryer, drill, microwave, etc...)

 # Limitations
 
-* **Artificial Environment:** Because it uses an isolating tranformer and artificial loads, it may not capture some of the noise experienced in real-world environments.
+* **Accelerated Testing:** The loads are activated and the measurements are recorded within an accelerated 20 min period. The ratio of base to peak loads in skewed in favour of peak loads. 
 * **Manual Calibration:** The accuracy is dependent on the manual mapping performed against the Shelly 3EM. Other methods are under development to perform calibration through automation.
