I have heard of the massive trailer-sized load banks used to do commission testing on power plants. It would be interesting to see one of those sucking up +150MW.
Handy device. I'd like to find a smaller one for testing homeowner grade backup and standby generators. particularly if it has waveform and harmonic analysis like the Fluke power quality meter I can't justify buying until I hit the lottery. With the prevalence of harmonics and power factor issues in the entertainment industry heavy power applications, we have to we sometimes have to oversize the neutral in feeders and specify K rated transformers, which might be useful thing for a future video. this is also a thing with switching power supplies in electronics and computers.
Thanks for the comment -- I guess I should have mentioned that on smaller gensets (single phase (15-45KW) that we install in homes -- we built a tankless hot water on a back board with breaker panel and cams) We also have a piece of equipment that we use to measure voltages -- harmonic distortion - ect -- I could do a video on that gear as well the test gear is AEMC -- thanks for watching --
Are all of your standby power generators for general use or do you get into any of the life critical stuff where you have 10 seconds from the first gitch to be up and online like healthcare facilities? It always fascinates me to se a large genset come up to full load from a dead stop and not overseed by more than 3 hz. and then have another genset come online and automatically phase match. It's been probably 30 years since I was involved with power generation but still very interesting and much more advanced electronics controlling the process.
thanks for the question - yes all of our gensets meet those requirements typically utilize a PMG system (permanent magnet) that provides a smooth representation of the frequency (speed) -- the controller then has an algorithm and electronic control of the injectors and pump so that precise speed control can be achieved along with load prediction and prevent overshoot -- this has also allowed smaller gensets to start larger motor loads (lock rotor issues -- basically a huge dead short when a motor starts) --- this units are also provided with heater to keep the coolant and oil warm so the genset isnt harmed by going straight to speed (1800 rpm) and take load almost immediately -- thanks for watching -- we also do make before break transfer switches that allow restoration of load without an blink by actually syncing the frequency of the two sources -- gen and normal supply ---

Awesome video, would love to see more!
Thanks! Will do!
Your videos are fascinating, I really appreciate you sharing the knowledge. 👍🏻👍🏻
So nice of you -- I dont know how much knowledge I have -- I guess I know a lot of things that dont work -- lol -- thanks for watching
@@ParkerSystemsAlways learning, even from mistakes.

heck yeah -- that would be cool -- can you imagine the heat that would be coming out of that thing -- thanks for watching
Thank you for your video I really needed this
no worries thanks for the comment -- thanks for watching
Nice Pete and video and information
check out our other videos - we a did a little high lite on that truck -- thanks for watching
About to test a 60Kw 3 phase, i feel more comfortable after watching this.
cool - glad it could help -- thanks for watching
Can the load bank be connected on th line side of the ocpd with no protection on the conductors
sure as long as the wire utilized is equal to or greater current capacity as the protection device. - -

thanks for the technology update@@ParkerSystems
It makes my battery load tester feel inadequate.
what size load bank is required for a 4.16kV, 1500KW Natural Gas Generator (CAT)
1500kw. Was this a trick question. You’ll need a transformer to get it to 480 volts. Thanks for watching
Interested in having one
if you are going to service genset valuable tool -- thanks for watching
Doesn’t mean we don’t need to be on guard.
I agree. Thanks for the comment
