Industry Solutions

Energy generation and distribution facilities require the strictest electrical inspection regime due to high voltage, large site areas, and continuous operation. We are with you every step of the way in solar/wind power plant investments, from site acceptance to periodic inspections.

Priority periodic inspections in this sector

The main inspections are prioritized according to your facility's risk profile:

Solar power plant / photovoltaic system inspectionPerformance and safety inspection of the panel, inverter, DC/AC side, and grounding.
Transformers and high-voltage equipment.Network connection reliability and failure risk management.
Grounding, step and touch voltage.Critical for life safety in large areas.
Lightning and surge protection (SPD)The biggest threat to equipment in the open field.
Power quality and protection coordinationVerifying harmonic, interrupt, and protection settings.
