Very good. Thanks 🙏🙏🙏🙏🙏🙏

Please share loss of excitation protection and all kinds rotor rekat use

Sir pole slip protection ke upar video kab aayega boliye full package banaiyega setting ke saath

Dear, please give some time.

@@gyaanELECTRICAL Ma, do generator dekha, Ek me pole slipping hai to usi me loss of stability nahi hai, dusra me loss of stability hai to usi me pole slipping nahi hai ,to mera doubt hai ke pole slipping aur loss of stability same hai?

Sir, Generator ke p.f jab leading hota hai tab stator flux aur rotor flux add ho jata hai, ie ,armature reaction fully magnetized ho jata hai , to isme over fluxing hone ka Shambhabna raheta hai keya? sir over fluxing & armature reaction ke sath kuchh relation hai Kaya?

[@gyaanELECTRICAL]

Dear the thing you are talking about is happen in air gap not in stator or Rotor core. So if armature reaction happen the additive and subtraction in flux happen in air gap, not in core of stator or Rotor.. So that does not impact on core. Hence overfluxing or armature reaction dono alag he.. armeture reaction ki effect overfluxing pe nahi ati

Thank you sir, my doubt is clear.but ek generator island mode pe vi chalte hai tabvi usse leading p.f mai kiu trip karana chahiye?

[@gyaanELECTRICAL]

Sorry don't understand your question, please elaborate your question ❓

[@mrityunjoybhattacharjee8472]

Generator jab Grid power or nahito dusra Generator ke sath ek i BUS me connect he to isko synchronising mode bolte he..Agar ek Generator Akela hi BUS me power supply kar raha he.. to o Bala situation ko Island mode Bola jata he.. Aab mera question he..ke island mode ho yia synchronising mode, Generator ka power factor always lagging hota he.. Agar leading power factor me chalega to iske reactive power reverse ho jata he.. aur reactive power reverse hone se digital meter me value ke aage negative sign (-) dikte he.. to Generator island mode me chal raha he, o only load ke sath Jura he tabvi ise leading power factor me reactive power negative hi raheta he.. to ye negative reactive power Agar set valu me chala Gaya to Generator trip hota he.. To iye tripping kisliye Dia jata he..?

[@gyaanELECTRICAL]

Because dear, If generator operate in leading power factor that means you are not giving enought field current to rotor. So that of field current not sufficient then the magnetic field generated by that is quite low hence voltage at generator terminal going to reduce or if that reduce more then permissible limit generator gets trip. So to generator rated voltage at terminal side you need to give some minimum excitation and if that excitation reduce below set value generator need to be trip. If you see our video on generator capabilities curve we have uploaded then it might cleat you doubt..

If generator me core saturate ho jaye to kya kare sir??

[@gyaanELECTRICAL]

Voltage hi generate nahi hoga
