It's the voltage: HT high voltage LT low voltage Tension = voltage (French?)
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.
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.
ht motor is to be fed with more than 415v like in kvolts. all the other operated below 415 volts are lt motors

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
The 1999, 2000, 2001 C70 engines that are HT are the 2.4 L Engines. The LT engine is the 2.3 L but it produces more horsepower than the HT.
