Service-Specific FAQs
Do you compile single-line diagrams for SEC clearance?
Yes. Our design engineering division compiles certified Single-Line Diagrams (SLD), load balance schedules, and earth testing reports conforming strictly to Saudi Electricity Company (SEC) and local municipality requirements.
Can you handle high-load substation equipment installation?
Absolutely. We handle utility transformer rigging, medium-voltage cable splicing, switchgear assembly, power factor correction panel setups, and grounding grid layouts under complete engineering supervision.
What testing do you perform before project handover?
PGL performs detailed pre-commissioning tests including insulation resistance testing (Megger), loop impedance testing, phase rotation analysis, ground-grid soil resistance tests, and active load bank testing under supervision.
