Answer / tarun aggarwak ymca
765kV, 400kV,220kV,132kV , 66kV,33kV,11kV
The substations can be classified in several ways including the
i) Classification based on voltage levels e.g.:
AC Substation: EHV, HV, MV), LV;
ii) Classification-outdoor or indoor.
Outdoor substation is under open sky. Indoor substation is
inside a building.
iii) Classification based on configuration, e.g.:
a) Conventional air insulated outdoor substation or
b) SF6 Gas Insulated Substation (GIS)
c) Composite substations having combination of the above two.
iv) Classification based on application.
a) Distribution substation
b) Switchyard in Generating Station
c) Switching substation (without power transformers)
d) Sending-end substation
e) Receiving substation
f) Factory substation
g) Compensating substation e.g. having static var compensation etc.
h) Load substation, e.g. arc-furnace substation.

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?

what is the significance of cabability curve of alternator
I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
