Actually DG size has to select depends on maximum demand
and considering base load and starting load and step load
base load = total maximum demand - loads which are
taking high loads at startign
starting load = if motor loads are DOL starts 6 times to
the Ifl will take at starting and soft
starters /VFD's will take 3 times to Ifl
step load = Whwn the main power supply is off
immidiently what are the load we can
switched ON through DG -called step load
(generally 40-60% of Dg load can be ON as
first step)
So our selected DG shopuld meet the step load and capable
to withstand startign loads

write circuit diagram for a motor rotate in forward direction once it started and when pressed the same button it should rotate in anticlockwise.
I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
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 ?

In both 600/1000 V cable and 450/750 V cable, we can supply 415 V. However for distribution, all utilities are using only 600/100 V instead of 450/750 V. What is the reason?
