Answer Posted / raul
there are basically two purposes for slip rings n brushes
in slip ring rotor......firstly they r used to short ckt
the rotor windings while in the squirel cage motors the
rotors winding r in-built short ckted by d heavy end
rings..........secondly they r used for speed control of
the motor by connecting external resistors wid the help of
slip ring n associated brushes.......

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
