Product Introduction
RATA's 7500kVA Resistive and Reactive Mobile Load Bank System is a high-power testing solution engineered for large generator sets, power systems, marine diesel generators, gas turbine generators, and UPS systems.
The system delivers 6,000kW of active power and 4,500kvar of reactive power, with an adjustable power factor ranging from PF 0.8 to 1.0. It provides independent control of the resistive and reactive loads, together with modular forced-air cooling and dual power supplies featuring automatic fast transfer for the cooling fans. Equipped with PLC-based intelligent control, the system incorporates comprehensive protection functions, including temperature, airflow, short-circuit, overvoltage, over- and under-frequency, insulation, and smoke protection. Supporting steady-state, transient, step-load, and automatic testing modes, it can simultaneously acquire, record, and analyze test parameters while generating detailed test reports. This provides a safe, accurate, and traceable solution for large-scale power system performance verification.
