Load banks are an important part of emergency backup and prime power systems. They are essential for testing, verifying, and exercising a power system’s ability to handle a required electrical load and are increasingly being used as an essential tool to maintain generator reliability in applications where exhaust after treatments are necessary to meet emissions standards.
Testing, Verifying and Exercising Power Equipment
Load banks are a key element in ensuring that an emergency backup power system can handle the required electrical load in the event of an actual utility power failure. Load bank testing simulates an electrical load and applies it to the backup power system. This can test everything from the automatic transfer switch (ATS) to the diesel engine and alternator, to make sure the entire system is operating properly.
To meet certain code and maintenance requirements, backup power generators must regularly be tested and exercised. The National Fire Protection Association (NFPA) has set requirements regarding acceptance testing and periodic on-site testing and maintenance of emergency and standby power systems. It is required that emergency and standby/backup power systems be tested and verified under load, and this is accomplished using a load bank.
