How Portable Load Banks Ensure Power Supply During Emergencies

How Portable Load Banks Ensure Power Supply During Emergencies

A fully functional backup system is the reason behind the success of a business and a long-running event. Well, depending on the place and time you can rent standalone or portable loadbanks. So, what is a loadbank? Loadbanks can assist you to learn everything about the performance of the power supply unit under the full or partial load. Well, before delving the details, you should know load banks are used for testing the power supply at the electrical outputs of a diesel generator, gas turbine and UPS systems during maintenance and commissioning. 

While talking about portable load bank, they can be rented from those who provide generator services, and they are driven to the site using a trailer. Most loadbanks come with incremental switching that let the generator be ramped-up and hence protect the loadbank from “block loading”. 

Portable reactive loadbanks:  Reactive loadbanks are used to simulate systems affected by the power network, electromagnetic devices and electric motor. The required equipment for such power testing system is capacitors, transformers and a motor driven device.  Based on the expected load from the power backup system, loadbanks simulate capacitive or inductive load. 

How to install them?

Moving loadbank is not as easy as moving a portable unit on wheels. However, container loadbanks and trailer are very portable. Upon mounting the loadbank on the trailer, portable reactive loadbank can be used to test the power supply unit at multiple sites. A truck attaching trailer simply drives the trailer from one location to another. Even if the container loadbank comes large, it is portable.  After reaching the site, the loadbank is unloaded from the truck using struts and telescoping leg extension. 

Loadbank safety during testing:

Go for reactive loadbank rental to perform the loadbank test safely for the generator and other power backup system in the building. The loadbank should be placed parallel with the building. The proper way to connect the loadbank is arranging a dedicated trailer with an over current protection device inside the vehicle, whereas the trailer will be located outside of the generator building. 

A list of recommended procedure to conduct the test: 

In the event, when a portable generator fails during the test or if the generator is identified as faulty one to get any further repair, the loadbank would be loaded back into the bus.  Here is a recommended procedure to conduct the loadbank test-

• Give generator the start and run it until the temperature stabilises.
• Shift all the automatic and manual switches to the emergency source.
• Until the desired load is reached, it is better to step-load the generator.
• Try to remove the loadbank before undertaking any other activity after the testing phase.
• Get all the transfer switches back to the normal position. 
• Go by the manufacturer’s guideline to let the generator cool down. 

Due to the continuous need of energy for a smooth performance of tasks, generators are most in demand. At times, the irregular power supply can harm different type of business operation. Be it a medical cause or a mill running high capacity equipment needs a undisrupted power supply that a well-functioning generator can assure. Loadbanks depict the actual capability of a generator and make people cautious while supporting an emergency situation.
