Hi guys,

I have attended a interview where they have asked me few questions, I need to know some...

1. what is the different between CGS system and MKS system?
2. When we connect the capacitor Banks in Series with the circuit?
3. What is the difference between Earthing & grounding?
4. how much voltage is present in neutral resistance?and how much voltage is present in earth resistance?
5. What is the purpose of calculating knee point voltage for Current transformers?

Awaiting your answers..

    Hi,

    I agreed with you. Any way, your ideal make me thinking about some thing for my project.

    2) to reduce capacitive reactance in the line
    3) sorry .. i think both are same .. may be the question will be diff b/w neutral and earthing ???
    4)voltage in neutral is zero

    i also attend the my interview questions
    1.if the diesel generator capacity 50kva but we are loading 20kva, suddenly the DG load increases suddenly 10-20kva what happens?
    2.in power plant how much pressure in boiler
    pls answer this questions

    1. Both CGS n MKS are measuring standards. In CGS system, length is measured in Centimeter, weight in Grams and time in Second.
    In MKS, length is in Meter, Weight is in Kilogram, and time is in Second.

    2. we r connecting capacitors bank in series with circuit to
    a) To remove the low frequency noise signal,
    b) To decrease the capacitive impedance.

    3. earthing means providing low impedance path to the circuit. And earthing wire is always ends in earth surface. Grounding means proving a Zero reference level to whole circuit or system. With reference to ground level, voltage at other nodes is measured.
