AMF means auto mains failure panel, actuvally it is a watch
dog, it always monitor the AC input source, if there is any
failure or any abnormality in the input supply, immediately
it will disconnect the load from main source and change the
load path on generator and also it will send start signal
to gen set. when after resumtions of main AC supply it will
check the healthy ness of the supply if it is healthy then
with little time delay it will change over the load on main
source and also sends stop signal to the genset.

hi frnz,can somebody give me any project work? i am a 2nd year student & interested in practical works...plz give me some projects
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?

when we design electrical schemes of 11/.415kv distribution..wen and were should we show the relays??what is the function of it?for example..we place EFR Relay CT between transformer neutral link and transformer earth.Like this what are the other type of relays we should use?why?where?Explain please..Thank you
how can i get the formula to find out the cable size if i know the load of main fuse protection.
When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
