Electrical Studies & Analysis
Electrical modeling of the system and simulation of the scenarios that matter: faults, motor starting, contingency and steady state. The result is not a loose number — it is the settings table that goes into the relay, the limit that goes onto the label and the list of what has to change in the installation. When nameplate data is missing or does not match the field, the study says so before calculating on top of a wrong premise.
What is delivered
What is delivered
Evidence of delivery
Calculation records, the system model, the settings table and a report of prioritized non-conformities.
- An electrical model of the system, delivered and reusable
- Short-circuit study and withstand verification of the installed equipment
- Protection coordination and selectivity, with a settings table per relay
- Arc flash: incident energy and approach boundaries (NBR 16384 / NFPA 70E)
- Load flow, voltage drop and motor starting
- Power quality: harmonics, unbalance and power factor
- Calculation records and a prioritized list of non-conformities
Scope
What's included
Each track is contracted on its own or combined. Whatever does not fit your operation stays out of scope — and out of the price.
Short-circuit
Fault current at each bus and verification that the installed equipment can interrupt and withstand it.
Coordination and selectivity
Curves set so a fault clears the smallest possible section, delivered as a settings table per relay.
Arc flash
Incident energy, approach boundaries and PPE category per work point, with labels for the field.
Load flow and motor starting
Loading, voltage drop and starting sag, scenario by scenario — contingency included.
Power quality
Measurement and analysis of harmonics, unbalance and power factor, with the correction sized.
Earthing and ground grid
Measured soil resistivity, grid verification and calculated step and touch voltages.
