In the energy and electrical infrastructure sector, testing is not merely the final step of the production process; it is the phase that distinguishes a standard system from one that cannot afford to fail.
When discussing testing in the medium voltage world, we refer to a series of specific evaluations designed to verify safety, robustness, regulatory compliance, and the real-world performance of equipment. Not all tests are the same, and they are selected based on the specific needs of the project:
- Electrical and Mechanical Testing: insulation tests, continuity, repeated maneuvers, and visual inspections.
- Functional Tests: we check logic, interlocks, protections, and commands. Everything must operate flawlessly.
- FAT (Factory Acceptance Test): this is always a crucial moment. We verify configurations and functionalities alongside the client. It is the most “collaborative” part of our work, a phase where improvement ideas often emerge and operational doubts are resolved.
- Type Tests: while we do not perform these internally, they are fundamental as they certify that the product family is designed according to international standards.
Why do we focus so intensely on this?
Mainly to guarantee system safety and efficiency. Failures are expensive; they stop plants and create logistical headaches. A well-executed test eliminates 99% of field surprises. Furthermore, safety is critical: proper testing minimizes the risk of internal arcs and explosions.
The Skills of a High-Level Testing Engineer
A good testing engineer must have a sharp eye for detail, the ability to read complex diagrams, and the intuition to spot inconsistencies immediately. They must possess deep knowledge of relays, logic, and SCADA systems.
This role acts as a bridge between various players, from production colleagues and technicians to the final client, communicating fluently in their native tongue as well as in English or other foreign languages.
Our testing team boasts expertise born from field experience, working in synergy with technical and production offices. They know the switchgear “from the inside out”: they know exactly where to look, what might cause issues, and which details can never be underestimated.
Another advantage is the relationship with the client. By interacting directly with customers during FATs, they build a collaborative partnership focused on achieving shared goals.
