Advances in Load Banks for Generating Set Testing
Load bank control and instrumentation systems have developed significantly over recent years. With the introduction of advanced load control systems the instrumentation has become an integral part of the system providing close loop control.

The Role of Load Banks in Gen-set Testing, and the Growing Need for Non-unity Power Factor Tests
Quality standards and the ISO 8528 for engine-driven gen-set testing demand that complete testing is carried out, but there are often misconceptions about what non-unity power factor loading really means, and the need for resistive and inductive load banks to truly prove gen-set performance.
