load bank for testing 5000 kVA generator

load bank for testing 5000 kVA generator

load bank for testing 5000 kVA generator

(OP)
Hello,

I'd like to test 5000 kVA generator performace by connecting a load bank. Any one ever purchase it and testing a emergency diesel generator? How much budget I shall prepare for one load bank? Thank you.

RE: load bank for testing 5000 kVA generator

Thats a 5MVA standby generator? Mind telling us what its backing up?

At 2MVA IEC style LV sets start to get a bit silly for current, and I don't know that MV load banks would be easy to come by.

RE: load bank for testing 5000 kVA generator

We use 11kV 3MVA load banks on our site. They were manufactured by Crestchic Ltd who are still in business.

RE: load bank for testing 5000 kVA generator

On a previous project, a 3MW diesel operating at 13.8kV used a 2MW LV load bank made by Avtron (USA), a permanent connection via a 2MVA step down transformer. But their web site indicated that they also make MV load banks up to 15kV and 7MW: http://www.avtronloadbank.com/permanent_load_banks...

This is a 13.8kv 5MVA DG connected a with a MV bus of a newly built power plant.
Our goal is to exam the AVR performance, bearing lubricant system and cooling system during generator full or no load. Consecutively Starting generator at full load, voltage droop..etc.
Thank you.

RE: load bank for testing 5000 kVA generator

So, why not just use the power system as your load bank?

RE: load bank for testing 5000 kVA generator

My initial impression was that you wanted to have a permantly installed load bank for regular standby diesel testing, which is typically the case for installations where the grid feeds the loads while an emergency stanby diesel is used for critical loads only when the grid is down. As it may take years in some cases for grid to go down, some places do install a permanet load bank for regular periodic generator testing.

But if that is not the case at your facility, why would you need need to purchase a load bank? Why not rent one if you need it for a week or similar to test governor and AVR reponse or so? Sounds that you may be a PM with no electrical background and if so perhaps getting some electrical help would be practical at this stage...

RE: load bank for testing 5000 kVA generator

Chrestchic makes a very good series of loadbanks, and has offices all over the world, can support rentals or sales
http://www.crestchic.co.uk/

Aggreko is a large company with worldwide offices, US link,

How about going back to your engine/generator supplier? Most larger suppliers have resources for testing, both short term and sales.

You might get better answers if you could provide where you are in the world.

Another load bank supplier to consider - SIMPLEX (Springfield, Illinois).

RE: load bank for testing 5000 kVA generator

Cressall Resistors have been in the business a long time in one guise or another. I'm more familiar with their neutral earthing resistors than load banks, but their quality is generally good.
