3750 KVA Resistive/Reactive Load Bank For Geneartor Testing
Keyword:
Ratas's 3750 KVA Resistive/Reactive Load Bank is designed for diesel generators, gas generators, and backup power systems to perform factory acceptance testing, on-site commissioning, full-load testing, step-load testing, and annual maintenance tests. They accurately simulate real-world operating conditions with a combination of resistive and inductive loads.
This load bank is typically configured for a Power Factor (PF) of 0.8 lagging, aligning with the common requirements of most generator sets and prevailing international testing standards. It allows for comprehensive performance evaluation through adjustable resistive and inductive load steps, facilitating tests at various load percentages.
The RATA 3750 kVA Resistive-Inductive Load Bank supports standard generator output voltages of 400V, 415V, 480V, and 690V. It offers customizable configurations based on your generator's specific rated power, current, and applicable testing protocols to guarantee secure and reliable loading during all test phases.
