Services
Electrical and instrumentation services
YGO Electrical Industrial Services provides specialist E&I support to main contractors during the construction, commissioning and handover of industrial installations. YGO works under contract within the project team, on industrial sites across the Netherlands.
QA/QC documentation and site coordination
WhenA project needs quality dossiers, inspection test reports and non‑conformities managed through to system handover.
YGO completes and manages inspection test reports (ITRs) and logs them in completion systems such as GoCompletion, coordinates inspections with client representatives, and follows punch lists and corrective actions through to close‑out.

Installation inspection and test witnessing
WhenConstruction progress needs installations checked against the project specifications and Dutch standards.
YGO checks single‑line, wiring and vendor diagrams and P&IDs, witnesses busbar, MV cable and transformer installation and hi‑pot tests, and performs micro‑ohm tests on busbar connections.

Commissioning and loop testing
WhenThe installation reaches the stage of field instrument connection and start‑up.
YGO carries out megger, point‑to‑point and 4–20 mA loop tests on field instruments and control cabinets to NEN and DIN standards, and supports start‑up.
