Generator Sizing Hub | Application Guides

Ukuran Generator by Application

Correct generator sizing is critical for reliability, efisiensi, and code compliance.
Undersizing causes overload; oversizing wastes capital. This hub provides application-specific sizing guides.

The 5-Step Sizing Process

1. Load Inventory: List all electrical loads with starting kVA
2. Apply Diversity Factor: Not all loads run simultaneously (0.7-0.9)
3. Select Power Rating: Prime vs Standby vs Continuous
4. Apply Derating: Ketinggian, suhu, humidity corrections
5. Add Margin: 10-20% future expansion

Common Sizing Mistakes

• Matching nameplate: Motors have 6-8x inrush, requiring 3x generator kVA
• Ignoring Faktor Daya: Low PF (0.6) requires larger generator
• No redundancy: Critical apps need N+1 (RSUD, pusat data)
• Skipping derating: High altitude requires 3-5% power reduction per 300m
