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
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

A 'bushing' is a tubular insulator used to insulate a conductor that passes, for example, from the inside of a transformer or circuit breaker to the outside, enabling the internal components to be connected to external supply lines.High-voltage (or 'high tension') bushings have thicker walls and are longer than low-voltage bushings, as they have to withstand higher voltages.
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).
HT drives are the pumps or motors operate at more power typically more than 0.5 Amps at 110 or 220 V DC whereas LT drives operate at lesser power less than 0.5 Amps at 24 V DC or 240 V AC.
It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
lt pannel is a iow tensan pannel. lt pannel work is 240v and 440v. ht pannel is a high tensan pannel . ht pannel work is 11kv,33 kv ,66kv, 120kv
1 ampere in high-tension (HT) is equivalent to 1 ampere in low-tension (LT) systems. The difference between HT and LT lies in the voltage level they operate at, with HT systems operating at higher voltages than LT systems.
An LT panel is a device that receives power and distributes it to other devices and boards. An HT panel is the same thing except it is used for high tension cables.
ht motor is to be fed with more than 415v like in kvolts. all the other operated below 415 volts are lt motors

The different testing steps of HT and LT panel include commissioning, sanctioning, erection and the CPP set. All this is done in the servicing of the transformers and the HT/LT control panels.
