Answer / pratik

both r diffrent coz in choke heat is dissapiated n it
consum more energy than eletronic choke electronic choke
save 40 to 50% energy save

Answer / anooj g krishnan

normal choke contain huge no
of coils. it posses high
inductance and low
resistance.so this type of
chocke work work on the basis
of self inductance.

but the electronics chock
contains some circuits
components.they increase the
frequancy of ac to much
highter value.

Answer / rajeev chaurasia

In Normal choke copper loss is high and operate at low pf. Hence it consume high power for same output while electronic choke operate at high pf and loss is negligible .

both are similar

in a solar power plant,we are going to step up the voltage 350V to 33kv, and to 132kv GSS. i want to ask that if it is possible that 315v/33kv is not possible because we also use 315v/11kv. or it should be 415v/33kv? is it effects generation or losses?  the second question is-generation is depends on LV winding? or LV winding design for generation voltage?
