For businesses relying on generators across Pakistan, unexpected breakdowns during power outages can be catastrophic. At ARSL, we’re revolutionizing generator maintenance through predictive load bank testing – a proven method that identifies potential failures before they occur, saving you thousands in emergency repairs and lost productivity.

Why Load Bank Testing is Essential for Pakistani Generators

Pakistan’s harsh operating conditions create unique challenges:

  • Irregular power outages force generators to cycle frequently
  • High humidity accelerates component wear
  • Diesel quality issues lead to combustion problems
  • Low-load operation causes “wet stacking” damage

Our load bank testing services address these issues by:
✔ Validating true generator capacity
✔ Burning off harmful carbon deposits
✔ Identifying developing electrical faults
✔ Preventing catastrophic mid-outage failures

How Load Bank Testing Works

1. Resistive Load Testing

  • Applies calibrated electrical load
  • Tests kW capacity and engine performance
  • Standard for most routine maintenance

2. Reactive Load Testing

  • Simulates motor/transformer loads
  • Tests voltage regulation and kVAR capacity
  • Critical for sensitive equipment backup

3. Combined Testing

  • Most comprehensive evaluation
  • Replicates real-world operating conditions
  • Recommended annually for critical generators

The ARSL Load Bank Testing Process

  1. Pre-Test Inspection
    • Fluid checks
    • Connection verification
    • Safety systems test
  2. Gradual Load Application
    • 25% → 50% → 75% → 100% load increments
    • Performance monitoring at each stage
  3. Detailed Analysis
    • Voltage stability
    • Frequency control
    • Exhaust temperature
    • Fuel consumption
  4. Comprehensive Report
    • Performance benchmarks
    • Identified issues
    • Maintenance recommendations

FAQs About Load Bank Testing

1. How long does testing take?

Typically 2-4 hours depending on generator size.

2. Will testing damage my generator?

No – properly conducted tests extend equipment life.

3. Can you test rental generators?

Yes – we test all makes and models.

4. What’s the ideal load percentage?

100% load for 2+ hours provides best results.

5. Do you provide certificates?

Yes – formal reports for insurance/compliance.

Don’t Wait for a Power Failure!

A generator that starts but can’t handle load is worse than no generator at all. With ARSL’s load bank services:

✔ Verify true performance
✔ Prevent costly downtime
✔ Extend equipment lifespan
