FAMILIARIZE WITH THE FUNCTION AND OPERATION OF AVR IN ALTERNATOR SYSTEM, SEE HOW IT REACTS AND HAVE A BRIEF UNDERSTANDING OF SOME OF AVR'S ELECTRONIC SYSTEM BLOCK.

The regulator of my 7.5 KVA generator has corroded and I want to replace it with a new AVR just like this SX460. I understand this is designed for a brushless generator which requires a smaller amount of current considering that the AVR is powering a slave generator which in turn supply a bigger amount of current to the exciter of the main generator. The way I look at it is that the voltages are just alright for my generator and the AVR. I just want to know if its 4A continuous current in the output is adequate to power the exciter field of my generator. By the way its exciter resistance is 6.9 ohms. Thank you very much and keep up the good post.
sir new sub po, ask ko lang po if low voltage po sa bahay pwede po bang magamit un avr para mareach po niya un acquired power supply para sa pc ko po, pc ko po kasi 600w psu nya tapos voltages po niya 230v,dinerect ko po siya sa ac oulet umadar po pero parang walang power supply na pumapasok kasi po namatay un monitor ko,,,pls, reply slamat po
Important is the AVR will match the excitation voltage & current of the winding field. So check the alternator nameplate if it mentions about the excitation V & I, your AVR output must be higher than those values otherwise it will damage your AVR. Thanks
Good day sir. may I ask you about some ideas regarding Alternator AVR . what will happen if the AVR will encounter some unexpected trouble. how it affects the operation . ? thing as I have observed.
Good day, you cant set the rated V or it will not sustain the V once genset take the electrical load. AVR, A acronym stands for Automatic, then AVR should react to whatever loading conditions, if its defective then V will not be sustained and therefore produces a high current that will either trip the breaker or burn windings or blew up diode/s in the rotation diodes. Hope this answers your question. Thanks
Engine speed control is a totally separate unit such as LSU if used for parallel operation or simply yung mech gov lang nag maintain ng speed if single run unit.
nice sir,, sir ask ko lng ung genset namin bumagsak ung out put voltage ng halos kalahati 400v naging 237 v nlng tas herts naging 33 nlng.. tas sa rpm walang dispaly puro number sign ####. posible ba avr my problema non? tnx
Sir thank you sa MGA turo mo. Tanong ko lng po Kung among AVR na mas maganda ikabit sa 1125kva Stamford...may naka install po UNG 15amp po UNG fuse. Kasama sa AVR. TY PO.
Sir, kapag 12 v dc charger kinabit ko sa carbon slip ring, nagkakaroon cya ng 125 volts, sira na kaya ang avr, ano kaya boss avr suitable, 2 wire lang kasi yung nakalabas sa stator, buy ko ito 2econd hand, thanks sa answer,
sir Rolando need malaman ilan excitation Current pra pde makahanap ng compatible na AVR. Sa excitation V ok naman prang nsa 25 to 40vdc mag laro yan while loading, sukatan mo sir ilan ohms yun main field sa slip ring. Thanks
sir gud pm paano kung ang output nya sa pag start at walang load ay nasa 75vdc na?umiinit kasi ang exciter field at di maadjust ang voltage.sira na ba avr ko
Good PM sir, based sa informations mo sir. May probability na sira AVR, ask ko lang sir meron ba yan remote V adjustment sa switchboard? If meron need muna ma check if ok connection at nde open yung potentiometer, pwede din kasi mag cause ng high V ang AVR pag may open lines towards remote V adjustment at kung dun ka mag adjust wala din V reaction. Pero if ok naman yun at yun AVR wala naman fuse then I can confirm na AVR lang talaga issue nyan. Thanks
Sir. Gud day po pag kumuha ba ako ng training sa inyo magiging qualified naba ako sa pagbabarko? Currently working in saudi arabia as electrician but my role there is fire alarm programmer EST3/3X EDWARDS BRAND. In Riyadh metro projects.
Hindi po sir, you need to inquire from MARINA para malaman lahat ng requirements para maging ETR. Yung mga trainings namin sir are only for skills upgrading, kasi kahit naman ETR,ETO or Marine Engineer na eh kulang padin kaalaman kaya itinuturo namin para mas magampanan nila trabaho na mas competent at kayang kayang ipaliwanag na superiors nila. Punta ka MARINA sir. Thanks
May tanong lang ako sir about sa generator namin after ma synchronize sa automatic mode in 10 minutes bigla nalang babagsak yng rpm at frequency ano kaya cause sir kasi pag ilagay sa manual mode ok naman
Sukatan mo sir voltage ilan output ng stator windings, if wala kasing input AVR then definitely wla din yun output. Kya check muna stator output if ilan residual voltage. thanks
Sorry mate, but this was made specifically for Filipinos only, so fortunate that we can speak both tagalog and english. To those who appreciates my posting thanks alot. Cheers mate🍻
sir my tanong poh ako meron akong genset na 15kva after ako nag palit ng universal avr walang out put na lumalabas piro kapag kinalabit ko yung J K saka pa sya nag wo work
