How to Conduct Loadbank Testing – A General Overview

When loadbank testing is conducted, a generator is burdened by an artificial load. A definite timeframe is stipulated for the test, and with the passage of time, the KW load on the generator is increased at a specific speed and at definite intervals. Every time a KW load is added, the test calculates and at the same time records the critical parameters of the engine. Alongside, the ability of the generator to handle the added boost and its capacity to function at the highest level for a considerable period is also calculated.

The equipment that is most needed to conduct this test is called a load bank. It is essentially a piece of equipment with a structure similar to that of a battery and is connected to cables.

Increasing The Load – How It Helps?

Placing a load of 100 percent capacity on the generators and allowing them to run for a specific period help the users to understand, whether the generator in question has any issue. Besides, it also helps to ascertain the health of the engine and the cooling system thereof. It also helps to ascertain whether the engine has any issue with its ring seatings. If any discrepancy is found that is amended by properly reseating the rings. Any gaseous build-up in the combustion chamber is also dislodged, and the valves are repaired, refitted or replaced.

Diesel engines, in particular, require periodic load testing for maintenance of health and checking fuel economy.

Different Steps of Load Testing

When it comes to load testing with the help of a rental loadbank, the technicians test the generators across a wide array of loads, through effective monitoring. It is backed by regular and constant monitoring and gathering of the data for a period of two to five hours, depending on the requirements.

1st Step

This step involves checking the level of every fuel of the generator. Making sure that fuel tank is fully filled, and a satisfactory level of oil is maintained. If the generator in question is a water-cooled one, it is also to be seen whether the coolant tank or the radiator is also filled up.

2nd Step

Now the generator needs to be started. The normal operating temperature should be allowed to be reached. Once that is attained, it is now time to listen to any abnormal sound or watch for any unusual behaviour.

Then subsequent actions are taken, which would involve taking further steps that will be determined by the nature of problems detected. If not, then diagnoses that are more intricate, are subsequently carried out.

However, that is a different topic!
