Generator AVR Replacement From 38V 1.9A to 60/80V 4A/5A

09/19/2017 9:08 AM

Dear All,

we have 125KVA Generator, whose AVR has been burnt, Its rating was 38V, 1.9A. Can we replace with ratings 60V 4A or with 80V 5A.

Thanks for your expertise in advance.

That's right, all 125 KVA generators are exactly the same. The same is true for the Automatic Voltage Regulators attached to these identical generators. The manufacturers just use different numbers for these items just so they can charge anything they want.

SNAP OUT OF IT!

Contact a licensed electrician or generator manufacturer to find out first why the AVR died. Then follow their advice if a new AVR or generator is warranted.

That is sort of harsh for us green-blooded goblins with pointed ears.

To go back and directly answer NKA: sure you can Oboober said yes you can.

Just make sure the new AVR fits in the hole left by the other one, and there is room enough for sudden expansion.

I politely disagree that this virtual dope slap is harsh treatment. NKA earlier thought that his motor protection circuitry damaged a motor. Now he wants our approval to replace a roasted AVR in an unknown generator for one with a bigger voltage and current rating than the one that roasted.

Unchecked, this Bozo can kill somebody.

...but but but what about, "yes we can"?

You are seriously raining on his parade, even if it is a parade to the undertaker.

The one he is putting in there will misbehave even faster than the previous did, if I read this correctly.

Clowns are scary.

No.

Go here Automatic Volt. Regulator‎

Or here Automatic Voltage Regulators - Safeguard Electrical Equipment‎

Or here Ask an AVR Technician Now‎

Finally here:

Asiapower Overseas Employment Services Employment Agency Navi Mumbai, Maharashtra, India +91 22 4225 0000.

There, you may find a job for which you are better suited and maybe more well qualified.

So basically, you can, you may even intend to, but this does not imply safe consent from this forum. Without knowing what you are doing, you may very well harm yourself or someone else in the immediate vicinity when this thing catastrophically self-destructs.
