Load Bank Testing
A Load Bank is a machine used to create a electrical load. Load bank testing allows us to mimic a full rating load that can confirm the product or equipment being tested can operate at its name plate rating. You can test generators, UPS systems, or anything that can have power flow through it. For generators this is important and often a requirment by governing jurisdictions, authorities, electrical codes and the actual manufacturer to name a few. On UPS systems you can see exactly how much life ths system has before depeliting its stored energy. We also use load banks to test various other products that need to be proven.
There are three common types of load banks. They are resistive, inductive, and capacitive. Both inductive and capacitive loads creates reactance in an AC circuit. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Capacitive reactance resists the change to voltage, causing the circuit current to lead voltage. A resistive load bank is the most common type. The use of grid type resistors creates the load.
