Feature


and cooling systems and alternator insulation resistance are effectively tested and system issues can be uncovered in a safe, controlled manner without the cost of major failure or unplanned downtime. Using a resistive reactive load bank can determine how well an entire system will withstand changes in load pattern while experiencing the level of power that would be encountered under real operational conditions.


The inductive loads used in resistive/reactive testing will show how a system will cope with a voltage drop in its regulator. This is particularly important in any application which requires generators to be operated in parallel (prevalent in larger business infrastructures such as hospital or data banks) where a problem with


one generator could prevent other system generators from working properly or even failing to operate entirely. Where a reactive-only load bank is used, testing should be increased to 2-4 times per year at 3 hours per test.


The Business Case For Load Banks Research published by Centrica in 20212 suggested that


only 50% of organizations are resilient to disruptions during extreme weather events or power outages. Properly planned and implemented, preventative maintenance strategies can minimise the likelihood of unscheduled breakdowns and outages, negating the potential risk of costly commercial, reputational and legal issues. Given the potential cost of downtime, it makes sound commercial sense to put a testing regime in place from day one.
