Mep 803a voltage regulator

[technoid]

My machine has the fuse installed to protect the field if the regulator should short. My question is does anyone know if a new improved regulator is available that has higher PIV rated diodes?

 

[Guyfang]

No. The Government never fixed the problem. And other problems could cause an over volt failure in any case. The fuse is cheap insurance.

I use to work for a public water utility. I was their senior electrician and technical trouble shooter. I worked on many large generators in the 350kw and up range. Our older units that dated back to the 1960's had outdated mechanical relay AVR's. I dealth with a company called Basler. All they needed was the resistance of the exciter field winding disconnected and the operating voltage. They had a solid state AVR for any generator. I upgraded many. And the responce time of the droop was so much faster. Since I am retired I am going to call them and see if they might have one for the 803. Maybe a much improved model thst wont blow out from start surge.

technoid, keep us up to date on what you find out, it would be good to have an option. Thanks

 

[technoid]

I will. They needed the info off the alternator ID plate. Soon as it warms up outside I will dig into it and write it all down.

Did you get anywhere with this?

I dealth with a company called Basler.

Basler makes excellent equipment, although also with an "excellent" price tag. Dewy must have liked their quality AVR's, since my four MEP-531A's all came with a Basler AVR.

Good work Kurt! I think you will soon be getting very busy, 802/803 replacement VR's have been a hot topic lately!

 

[Guyfang]

And how!!

Am I right in assuming the fuse mod will no longer be needed?

 

[kloppk]

Correct, no Fuse Mod or MOV Mod needed.
Also works in generators that have damaged Quad windings.

Would really like to have a spare voltage regulator for my 803A
