Studies
We carry out calculations in ETAP and PowerFactory, on our own licences. Scope and price are set at the outset, and every operating configuration is calculated.
In each study, we look for the worst-case configuration. We work in campaigns. The model is checked first, then in-house scripts run every relevant combination of upstream voltage, topology, load and tap position. Each result is checked before it is used.
The eight studies below are often combined. A protection plan relies on short-circuit and load flow, an arc flash study on the settings, a grid connection study on load flow, harmonics and dynamics. Each page describes the method, the data to provide and the typical offer.
01All studies
Load flow
Voltages, loading and losses in every operating configuration.
02EMT
Fast phenomena: inverters, energisation, switching overvoltages.
03Protection coordination
Only the protection closest to the fault should trip.
04Protection plan
Functions, current transformers, settings, settings schedule.
05Arc flash
Incident energy, arc flash boundary, PPE.
06Harmonics
Distortion, resonances, filtering.
07Stability
Critical clearing time, voltage dips, motor starting.
08Equipment sizing
Short-circuit, cables, transformers, earthing system.
