What Are The Key Reasons for Loadbank Testing?


The key reasons behind loadbank testing are that there are a number of generator sets, which will seldom run under the influence of full load, once they roll out of the showroom. Though tested with the compliance of all the regulatory requirements, which permit the use of several actual conditions may erupt, which can very well affect their reliability and performance. 

Load Bank Testing on Modern generators

Modern generator sets that run on diesel are designed to meet the most stubborn EPA Tier Level Emission standards, which are designed to be operated at loads that are higher than 50% for optimum life or performance. 

Besides, using the after-treatment particulate matter filters (DPF), which depends upon exhaust temperature for the regeneration to take place can be jeopardised by operation under a low load.

Also, a restricted outflow of the exhaust gas can lead to a buildup of, causing a back pressure of the gas more than the certified level. These will collectively restrict the operability of the reciprocating engine-generator set. 

Furthermore, unscheduled maintenance activities can also influence the functioning of the generator. This is where a thorough Industrial loadbank testing of these modern generators will come in handy in a number of ways. 

Loadbank Testing vis-a-vis Regulatory Requirements

Testing of loadbanks is an extremely critical component that meets the regulatory requirements. These days, diesel-powered generator sets utilise electronic engines, and emission controls go a long way to meet the present as well as the future EPA emission requirements. 

Large Capacity Resistive Reactive Load Bank 

As and when multiple units are installed, they are often operated individually for periodic as well as annual testing, with the use of test loads that are much lower than levels recommended by the manufacturers. 

Therefore, using large capacity reactive resistive loadbank will allow the simultaneous multiple-unit testing, thus cutting down the total time that it consumes to perform as well as document the mandatory testing. Additionally, they also exercise paralleling the controls under the most realistic conditions possible. 

How periodic loadbank testing helps? 

Periodic testing is as essential ad regular maintenance in every facility related to health care practices as well as other operation niches, to ensure that they comply with the respective regulatory bodies. 

It is a common practice of these facilities to perform regular and periodic testing of generator sets, during off-peak times, when the loads are at the lowest limit. While this helps to thwart the likelihood of severe aberrations and interruptions to critical or high-end loads, it fails to assess the capacity of the generators in worst-case scenarios accurately. This is where periodic loadbank testing helps.
