Hello Gentlemen, After many discutions with the nice guys from John Deere Factory and Stamford UK , it appears that the 110 KVA and 140 KVA generators have the same engine (4045HF150 with 16ME injection pump) and that the alternators are the same (UCI274D). so basically we can expect a standby...

after some investigations , it could be possible that the alternator might be a UCI274 , either C ou D (based on size of the housing) cause Stamford do not have the serial number matching with one of their model. we are going on the safe side , and according to the specs sheets from engine and...

Good evening , please let me tell you a story about two gensets of 3 generators each: the first one is powered by 4045HF150 John Deere engines , with Stamford UC224D alternators. rated to 110 KVA standby.we can call it George. the second one , powered by John Deere 4045HF150 and fitted with...

thread238-389899 Good evening Gentlemen, a quick update on the previous post , the hospital is now fitted with a brand new 1600 Amp ATS switch , very nice but heavy as a dead donkey :). transitions from city power are now much more safe. many thanks for the advices . Best regards Jean Michel

thread238-392721 a small update for the retaping problem in Haiti : we have been readjusting the output voltage of the generators to 208v , reprogrammed the 10KW UPS to the same voltage , setting the ATS values to mi 200/max 220 v , and adjusted the transformers to 208v. No more beeps ...

Dear all, we are going the have the transformers adapted to the 12470v line and adjust the AVR to 208 v, and see how things are going. thanks for the informations and advices ! best regards from Haiti Jean Michel

Thanks Melspuds (is this your real name ?!?). here it is not so easy to find such transformers , as they all come from Florida or US . the budget for the project is not extensible , I thinks we can manage to replace motors from time to time , and switch fluo tubes by led models. all criticals...

Thanks Dave, as you said , it's a mess. you could think this job was done by haitians who didn't have the chance to get a proper education and did their best to make it work. unfortunately this mess was done by a US company , who claim to have 20 years of experience in the field....[machinegun]...

indeed , in Haiti we are running almost 14h/day on generators ,and overheating of AC and (chinesse) ballasts are commons. about the ATS switch , i think it is the return from genset to main city power that cause brutal transitions. according to the configutation file of the DSE331 , the...

we are using Kutai BTS3BE800 transfer switch the DSE331 used for switching control is not synchronizing , since main transformers and generators nominal voltage do not match (196v for tx , 220 for gen), and the "genius vendor-installer-engineer who setup the power stations" doesn't have a clue...

indeed , and since the tranformer is a 13.200/208v , we will inject almost 14.000v in a 12.470 grid [bugeyed]. well , with the forum members support , i have now a strategy to correct those issues , many thanks. best regards Jean Michel

the fun part of the story is that the generators connected via an ATS are delivering...220/127 ![sadeyes] so we alternate between 196v to 220 and back , the transitions are rather brutal. we are losing AC units and fluo balasts at an accelerated rate. the plan to correct this issue is to re-tap...

Dear All, we have 3 padmount distribution transformers , rated for 13.200Y / 208y-120. the line voltage in Haiti is 12.470v. we keep on experiencing low secondary voltage , and the installer of the transformer tell us that it is because of grid power , not transformer. my guess is that the...

Dear all, investigating electricals circuits in 3 Haitians hospitals , i keep finding odd and stranges things. the lastest is a connection between padmount transformer and ATS switch cabinet. three phases , 220 v , 300 KW circuits are connected with the system show below : i am not an expert...

dear all, here is the reply from the manufacturer of the equipment , and by the way , the max current is 1600 amps : "Hello Jean, From your attached drawings, there are two concerns. 1. The switches' transfer speed are slightly different. When the ATS transfers from one side to another at...

Thanks Davis , i am going to ask thic company to review the design and go for a 800A ats switch. best regards jean mi

hello Gentlemen, a company is suggesting to use 2x400a ats switches in // instead of a 800a... as far as i remember , this is not a good idea , either in terms of repartition of current , and in term of switching timing. do you have any idea about that ? any help welcome. ps : this is for the...

end of the story : a Dominican company is going to check the transformer (insulation etc.), replace the damaged bushing and put insulations plugs in unused connectors. thanck to ABB and Eminsa . best regards Jean Michel

thanks again to all of you , this was very helpful.[thumbsup2] Jean Michel

many thanks guys , do you have some references or regulations for me to study about shipping caps ? unfortunately , the supplier / installer saw the word "sabotage" and as this sound good to him (cancellation of warranty and supplying us a brand new transformer ) i predict we 'll have a hard...
