Engetecnica manages and integrates highly complex electrical infrastructure projects, including the complete construction of power substations, new electrical power systems, and expansions or upgrades to existing systems.
By outsourcing your commissioning and integration activities to our expert team, your organization can stay focused on its core operations while we ensure a smooth, safe, and efficient start-up process for your power systems.
Thanks to our structured organization and multidisciplinary professionals, we deliver seamless execution — from planning through energization.
Equipment Testing
Using state-of-the-art instruments, we test all equipment in accordance with national and international standards to ensure performance, integrity, and long-term reliability.
Functional Tests
We verify electrical control, signaling, interlocks, and activation circuits to ensure accurate logic and reliable operation.
Protection Curve Validation
We confirm relay settings and selectivity studies, ensuring optimal coordination between protection elements.
Integrated System Tests
We perform end-to-end validation of electrical systems, including interlocks, automation, local and remote controls, voltage and current circuits, and logic diagrams.
Energization Monitoring
After final commissioning, we supervise the energization process to ensure proper functioning and safety of the installation.
