FAQ

Q1: What does RL mean in load banks?
RL means Resistive + Inductive. It combines resistive elements that draw real power (kW) and inductive coils that draw reactive power (kVAR), simulating real-world electrical loads with lagging power factor.

Q2: Why is reactive load testing important?
Reactive testing helps evaluate generator voltage regulation, power factor correction capability, and transient response — critical factors for reliable system operation.

Q3: Can GROADA RL load banks operate outdoors?
Yes, optional weatherproof enclosures (IP54/IP55) make them suitable for outdoor or mobile applications.

Q4: Can multiple load banks be paralleled?
Yes, GROADA RL load banks can be connected in parallel to achieve higher power capacity or multi-system testing.

Q5: How often should load bank testing be done?
Industry best practice recommends at least once a year for standby generators or UPS systems to ensure reliable performance and avoid carbon buildup.
