Why Vacuum circuit breaker is using HT and why Air circuit breaker is using in LT?
Dielectric Strength of Vacuum is more than that of Air. In HT voltage is more than LT. So VCB is used in HT & ACB in LT. Rakesh Gaikwad
What is the benefit of using HT Motors instead of LT?
to reduce Current and Coast
What precautions to be taken when working with Transformer?
Frist putt of the main incomer HT side then Rack out the breaker and put the LOTO after that Discharge the cable Both side (HT/LT).
Can you use HT cable in place of Lt cable?
For LT cable 1. Use : Up to 690V 2. Insulation : PVC 3. Core(Neutral) : Yes 4. Insulation Grading : 1100 V For HT cable 1. Use : Above 690 2. Insulation : XLPE 3. Core(Neutral) : No 4. Insulation Grading : Above 3.3kV, 11KV..etc ( Please note that now 690 V using in VFD application with LV cable and 440 V for DOT motor starter) from Kunal Singh Dabi the_dabi@rediffmaill.com
What is the difference between HT and LT line?
ht cable that means voltage level is high , it is obvious that power is going to remain same ,so if voltage rises ,current has to be lowered .since current level is less in ht cable therefore size (dia) is less compared to l.t cable , (p=v.i),lt cable current rating is more and voltage rating is less
