Resistive load banks are used to test electrical power supplies, with their primary goal being to detect issues to ensure the response capability and efficiency of the installed equipment. These problems are identified by simulating variable electrical load conditions, which are measured and recorded precisely in a controlled scenario to understand how the system would react to a real electrical failure. Therefore, it is important to perform maintenance and testing with resistive load banks to optimize and ensure the proper functioning of electrical supplies and to avoid fines and penalties.
