why we are not earthing ht cable at both the ends(sending &
receiving end)?

Answer / gunasekaran
if we connect at both end circulating current will flow so
Armour getting heated up if and then it will tripping for
earth fault protection.

Answer / felixraj
only signal cables should earthed at one end. HT cables can.

Answer / vinod
HT cable earthing only sending end, Why because in case of
earth fault relay pick up with minimum leakage.
| Is This Answer Correct ? | 1 Yes | 3 No |
Answer / j.kesavan
ht cables not connect earth propely current flowing through
the armours cable get more temp, thats why not connect earth

What will be the impact on motor performance if a LT motor is rewound with changed motor winding data as given below:- Original winding data: total 04 wires = 02 wires of 17 SWG + 02 wires of 16.5 SWG. Changed Winding data: total 03 wires of 15.5 SWG wire size Motor rating: 160KW, 740RPM, 415V, ID FAN application. Normal Running Current = 95% of FL Current.
need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
i am going to correct power factor of 1600kw induction motor,when i calculate capacitance of capacitor it is three time more in star connection than delta. if motor is star connected which connection i shall adopt for capacitors and reason for adopt this connection
