load resistors (dummy loads)

Mobile load resistors, also known as dummy loads, are essential tools for the maintenance and testing of generators and emergency power systems. These portable devices simulate an electrical load and thus enable the actual performance of generators to be verified under realistic conditions.

Functionality and Applications

Mobile load resistors are used to test generators under load without connecting real consumers. They make it possible to test the full capacity of a generator and ensure that it can reliably deliver the required power in an emergency. This is particularly important for:

Regular maintenance of emergency power systems
Commissioning and troubleshooting of power generators
Simulation of continuous operation in the low load range
Legally required monthly test runs

Advantages of mobile load resistors

Flexibility : Thanks to their mobility, these devices can be used flexibly at different locations, which is particularly advantageous for service technicians and when maintaining systems in different locations. Versatility : Most mobile load resistors have individually switchable load stages, making them suitable for power generators of different power classes. Ease of use : Many models are designed to be used by trained operators without any special electrical knowledge. Efficiency : They enable quick and effective checking of generator performance, minimizing downtime and increasing operational reliability.

Technical features

Mobile load resistors are available in a variety of designs, from simple trolley models to trailers for larger capacities. Typical features include:

Power ranges from a few kilowatts to several hundred kilowatts
Various connection options (e.g. 16A, 32A, 63A, 125A CEE)
Integrated cooling for safe continuous operation
Robust construction for outdoor use
Easy transportability through rollers or trailer construction

importance for operational safety

The use of mobile load resistors contributes significantly to the reliability and operational readiness of generators. Regular testing under load allows potential problems to be identified and resolved at an early stage, which can be crucial in an emergency when every second counts. Mobile load resistors are therefore an indispensable tool for anyone responsible for the maintenance and operation of power generators and emergency power systems. They ensure that these critical systems function reliably and deliver the expected performance in an emergency.
