What is a load banks?

Load banks are the best way to replicate, prove and verify the real-life demands on critical power systems. Ensure backup power availability when it matters most.

Load banks is a precise test device, apply loads to electrical power sources such as diesel generators UPS and dissipate converts power ino heat.

Resistive Load Banks

A resistive load bank can be used to fully test the generator set at 100% nameplate kW rating. It will also fully load the generator cooling, fuel, and exhaust systems. Only 80% of the generator set nameplate kVA rating can be achieved when utilizing a resistive unit. The resistive load bank will provide a unity or 1 power factor (PF) load to the system under test. Resistive units are predominantly used for AC voltages, however specifically designed DC load banks are also available.

Resistive Inductive (Combined) Load Banks

A combined load bank usually consists of both resistive elements and inductors that can be used to provide load testing at non-unity PF (lagging) including the capability to test the generator set fully at 100% nameplate kVA rating. Combined load banks incorporate resistors and inductors all in a single construction which can be independently switched to allow resistive only, inductive only, or varying lagging power factor testing. Combined load banks are rated in kilovolt-amperes  (kVA). It's worth noting that combined load banks can consist of resistive, inductive, and capacitive also.

Capactive Load Banks

An Capactive load bank is normally used in conjunction with a resistive unit to provide a lagging power factor load test.

Capacitive load banks incorporate industrial capacitors and increase the PFto above unity(leading).Capacitive load banks are rated in kilovolt-amperes reactive (kVAr).

Powerzoo manufacture from small portable solutions right up to containerized multi-megawatt units to meet the complex demands of any load test applications.
