1. Load Bank 負載測試器 RGR 高壓接地電阻器

2. What Is A Load Bank? (Dummy Load) Load Banks are devices designed to provide electrical loads for testing power sources such as Generators and Uninterruptible Power Supplies (UPS). Normal/Emergency Loads Load Bank

3. Why Are Load Banks Necessary? Maintain reliability of the Emergency Power System by testing of the engine generator (s) under load.

4. Testing With A Load Bank Will Help Insure   

5.    That When You Have A Power Failure   

6.    Your Engine Generator Will Deliver The Power It Is Required To Do!

7. Recommended / Required Testing Of Engine Generators Frequency Duration Capacity  Monthly 30 – 40 Minutes 50% to 60% of Engine Generator Rating  Annually 2 Hours 100% of Engine Generator Rating (Resistance/Reactance)

8. When it is unfeasible to apply actual load, it is recommended to use a Load Bank

9. Hospital & Health Care Facilities

10. NFPA Required Testing Of Engine Generators Hospital And Health Care Frequency Duration Capacity  Monthly 30 Minutes 50% of Nameplate Rating Of Engine Generator  Annually 30 Minutes 100% of Nameplate Rating Of Engine Generator

11. Please Realize . . . Your Generator Is Only As Good As Your Last Full Load Test! AC Kilowatts

12. Full Load Testing Assures proper KW, Voltage and Frequency AC Kilowatts

13. Full Load Testing Confirms the Reliability ofcomponents such asFuel & Cooling Systems

14. Another important reason to operate your standby generator under load…  Diesel…The Preferred Fuel For Standby • A Diesel Engine Generator Should Always Have At Least A 50 – 60% Load Connected While Running - - - Or “Wet Stacking” Could Occur - - -

15. Unburned Fuel Causes Carbon Build Up Excessive Oil Consumption Reduced Horsepower….Reduced Efficiency Premature Failure “Wet Stacking”

16. Wet Stacking Is Most Common . . . Applications With Varying Loads Engine Generators Sized For Pump Starting Currents And All Pumps Running At One Time

17. Wet Stacking Is Most Common . . . • Gen-Set Was Oversized For Future Growth Or Redundancy Emergency Bus N + 1 Engine Generators
