# 4 hi friends i m from electrical branch and seeking for tech. + apti. both papers of hpcl plz get it available as soon as possible my email id is sumit_lig189@yahoo.co.in
HPCL,
2003In all the generators, the excitation supply is DC. What is the significance of DC excitation? What will happen if AC supply is given as excitation supply?
2 5020if 2 coil of 1000W connect in series and 200 v is applied across it . then what is the total power of coil when coil have only resistive load .
BSNL,
1 2681how can we measure 220kv or more than these voltages ...?and also how can we conform whether we r getting 220kv from generating stations throuth the h v transmission lines?

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
