Answer Posted / gunasekaran
as per standard it is not same cooling is depending upon
the rated MVA percentage impedance depending upon the MVA
rating if low MVA %impedance is low if high MVA %Z is high
in standard upto30MVA we can use ONAN
upto60MVA ONAF
above 60MVA we can use OFAF
upto 1.5MVA AN
if customer asking we can use for colling method for any
rating.

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?

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
