elec calc™ calculates the different voltage drops within the electrical installation:
- Individual voltage drop of a component
- Overall voltage drop from the source to the receiver
- Voltage drop in steady state
- Starting voltage drop
The aim is to ensure that the overall voltage drops do not exceed the thresholds laid down by the standards or the specific constraints required by the user.
The voltage drop is calculated from the actual currents circulating in the phases and neutral, taking into account phase displacements caused by the impedances of the different components.
The voltage drop is calculated for a given operating mode in steady state and during start-up. Each start-up is considered in the most unfavourable conditions, therefore with the entire installation energised. Simultaneous start-up of several receivers is not taken into account in the current version.
Users can define specific voltage drop limits for receivers, transformers, UPS and VFD in steady state and if necessary during start-up. elec calc™ emits an alert if the defined thresholds are exceeded. An alert is also emitted if the thresholds defined by the user exceed the thresholds imposed by the normative texts, if any exist.
