Resistive / Reactive Load Banks

Resistive / Reactive loads are able mimic motor loads and electromagnetic devices within a power system as well as purely resistive loads by offering the ability to set a specific power factor (pf). Many backup generators and turbines are rated at 0.7, 0.8 or 0.85 power factor and need to be commissioned at nameplate capacity using a combination of resistive and reactive load to fully qualify their operating capability. Using a resistive / reactive load bank enables comprehensive testing from a single unit. ComRent has an extensive range of resistive / reactive load banks to simulate these types of loads on a power source and the transformers, relays, and switches which will distribute the power throughout your facility.

Inductive & Capacitive Load Banks

Inductive or Capacitive load banks are reactive only and must be used in combination with a resistive load bank to provide the desired load profile to test a power system. Reactive loads banks can provide either a leading power factor (Capacitive) or lagging power factor (Inductive).

DC & Electronic Load Banks

Electronic Load banks simulate solid state systems and are ideal for testing precision power and current with constant power. DC load banks are valuable for testing inverter/rectifiers in AC-DC conversion systems like those used in solar farms or DC power circuits. They are also used for testing battery backups and control systems.

Medium Voltage Load Banks

The ability to test critical power systems at voltages of 4160V to 15kV using direct-connect, medium voltage load banks offers engineers flexibility, time savings, and simplicity. ComRent International is the only provider of temporary, medium voltage load banks to commission utility, oil & gas, and industrial power systems without the need for additional transformers and cabling. ComRent’s inventory of resistive and reactive load banks supports substation, power generation, and industrial facility testing with precise, on demand, controlled load to ensure critical components and settings are validated before going into service.

ComRent International can also provide medium and high voltage transformers to support system tests as high as 230kV for critical Transmission and Distribution systems.
