What is LT and HT?

What is LT and HT?

LT (Low Tension) vs HT (High Tension) A low-tension line is a low voltage line and a high-tension line is a high voltage line. In India LT supply is of 400 Volts for three-phase connection and 230 Volts for single-phase connection.

What is the full form of HT in electrical?

In vacuum tube technology, HT or high tension describes the main power supply to the circuit, which produces the current between anode and cathode.

What are the types of motor?

Motor types for industrial electric drives

• DC Series Motor.
• DC Shunt Motor.
• Cumulative Compound Motor.
• Three phase Synchronous Motor.
• Squirrel Cage Induction Motor.
• Double Squirrel Cage Motor.
• Slip ring Induction Motor.
• Single phase Synchronous Motor.

What is HT motor?

Depending upon the voltage supply the motors are classified as LT & HT motors. LT motors called low tension motor and HT motor called high tension motor. As per Indian practice motor are classified as follows- LT Motor – Motors which work on 230 V, 415 V and 690 V.

What is HT power cable?

HT POWER CABLES Ideal for carrying current at high voltage, the HT cable range from Havells are manufactured at the largest integrated cable unit in India and use high quality copper and aluminium conductors. With benefits like high continuous current rating, higher short circuit rating, and longer life etc.

What is HT and LT panel?

HT Panels are generally used to supply power to various electrical devices and distribution boards. LT Panels are used with low tension cables to obtain power from the generator or transformer and distribute electricity to various electrical devices and distribution boards.

What are the 2 types of motor?

The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.

Which motor is used in grinder?

The motor used in your standard grinder is a universal electric motor, which works on both DC and AC current. The motor is wound with copper wire to produce an magnetic effect on the rotor.

What is the difference between HT cable and LT cable?

Application: LT and HT cables have various areas of application. LT cables can be used in industries like power distribution, power stations, railways, etc. While HT cables are used in power transmission and distribution that has a range greater than 1.1 kV.

Can HT cable be used in LT?

LT cables use materials like PVC while HT cables normally use cross-linked polyethylene (XLPE). Armoring is the protective covering for a cable and is present in both LT and HT cables. However, some LT cables can be unarmored.

What is the difference between HT and LT cable?

Low tension cables have a lower rating where as high tension cables have a higher rating [3.3kV]. Both cables are used in industrial setup and applications, but LT cables are generally used in applications revolving around the 1.1kV range and HT cables are used mainly in power transmission and its distribution.
