what is the difference between the HT Cable and LT Cable ?
Answer Posted / jacobdaniel
HT Cable:- 1) Its design having 4 to 5 layer of protection
to withstand the high tension voltage and also we can avoid
Voltage drop because of sensitive protection.
2)Bundle Conductor of HT Cable thickness is high than LT cable
3)HT Cable having R,Y & B Terminals without Neutral
LT Cable:- 1)Its design having 2 to 3 layer of Protection to
withstand the Low Tension Voltage.
2)LT Cable having R,Y & B Terminals with Neutral

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.

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
