an amazing situation was faced when an alive distribution panel with 415 volts and carrying almost 200Amps has become short and this metal cubical showing 220 volts against neutral and earth. to redress any confusion i checked the panel with help of single 200watts test lamp which also glowing with max.intensity b/w neutral & metal body of DB. amazing situation is that i hold the DB firmly more than once with necked foot means without insulated shoes but not received any electrical shock. whereas our all running gen sets neutral points also proper grounded and this short DB was completely earthed , this is beyond my understanding . any body explain how is it possible . our running gen set neutral also grounded firmly

sir please send me iocl written test paper in my e-mail account. i'll be obliged to you........ thank u roshan
hi this is hema, r there any books in particular for the preparation of the APPSC-A.E.E(electrical), if so please mail me the names ... thank u .
Can you used moeller lzm1 mccb in a dc system with 125vdc and 20ka short circuit current , beside is it have 24 or 48 volt shunt ? Beside how long current can through from An MCB shunt contacts? (like Z7-AS 24 V)?

Hi friends, i m electrical engineer i want a cdr for migration purpose so anybody have information about this then send me on jayesh_ee88@yahoo.com.please try to me
pls,send the previous year written test questions.
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
