why current transformer secondary is short circuited an what will happen if connect very high resistance acrossthe secondary side of current transformer?
1 3677when generator short circuit condition, the current how dissipates. or at short circuit voltage not available then current how can flow?
2148Generation of voltage for each phase are same of a turbogenerator.Although the short circuit current flow when two phase of turbogenerator are shorted(where current can't flow without potential difference),why?
2050How will A Medium voltage circuit breaker(11 kV voltage level) operate under short circuit fault condition whether It is having short circuit release like Low voltage circuit breaker or relay should be given?

CAN ANYBODY PLEASE TELL ME HOW TO DESIGN A SERIES REACTOR FOR LIMITING SHORT CIRCUIT FAULT CURRENT??
how we can calcultae the short circuit level for bus bar
what is the easiest method of short circuit current calculation ? pls. derive with a mathematical example in real life application.
How we can determine short circuiting current any plant and for example a plant which power generation is 415 volts and plant load is 500 kw.
Please clarify 1. Icw: rated short circuit working withstand capacity 2. Icu: Rated ultimate breaking capacity 3. Ics: Rated service short circut withstand capacity 4. other specification of ACB
how to determine the cable size...pls explain me with the formula taking particular load....does the factors like impedance & short circuit rating influence the cable size, if so how....
-What shall be short circuit current of LV switchgear for a 1000 kva, 11.415kv, 3 phase tranformer with 5% reactance.
following are the questions asked in interviews: 1) Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
To prove the capacity of a 10MVA transforemr with 6.5% impedance by a short circuit test how much power is needed to inject an impedance voltage if we have to arrive for its rated current?
why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
Why are short circuit ratings always 16kA,25kA,36kA and 50kA.Who has fixed these?
