What is the LT switchgear?
The term LT Switchgear includes low voltage Circuit Breakers, Switches, off load electrical isolators, HRC fuses, Earth Leakage Circuit Breaker, Miniature Circuit Breakers (MCB) and Molded Case Circuit Breakers (MCCB) etc i.e. all the accessories required to protect the LV system.
Where is LT switchgear used?
The LT (low tension) switchgear is used for circuits below rated voltage 1000 V A.C. or 1200 volts D.C.
What are the main functions of LT switchgear?
Functions. One of the basic functions of switchgear is protection, which is interruption of short-circuit and overload fault currents while maintaining service to unaffected circuits. Switchgear also provides isolation of circuits from power supplies.
What is a LT circuit?
There are different types of circuit breakers that are used for circuit switching mechanisms under the low tension (LT) and high tension (HT).
What is the use of LT panel?
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. LT panels are designed to function at lower voltages (up to 690 Volts) with low insulation levels.
What is LT and HT switchgear?
HT means high tension or high voltage, where in a small current is used with a very high voltage(for creating plasma). LT means low tension where in a low voltage is used with very high current(for heating the resistive boats). Cite.
What is the role of switchgear?
What is switchgear? Electrical switchgear refers to a centralized collection of circuit breakers, fuses and switches (circuit protection devices) that function to protect, control and isolate electrical equipment. The circuit protection devices are mounted in metal structures.
What is LT system?
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. High tension or HT supply is applicable for bulk power purchasers who need 11 kilo-Volts or above.
What is an LT board?
LT Panel is an electrical distribution board that receives power from generator or transformer and distributes the same to various electronic devices and distribution boards.
What is LT board?
Why L switchgear?
Electrical Business, viz. the design, manufacture & marketing of switchgear is one of L’s major activities. L is India’s largest manufacturer of low voltage switchgear and controlgear. Its quality management system for design, development, production, marketing and servicing has received ISO 9001 certification from BVQI, UK.
What is LV switchgear?
This switchgear has capacities up to 1 kV. Hence, the term LV switchgear collectively includes low voltage circuit breakers, offload electrical isolators, earth leakage circuit breakers, switches, miniature circuit breakers ( MCB ), moulded case circuit breakers ( MCCB ), and H.R.C. fuses. LV switchgear is present in the LV distribution board.
What are the components of switchgear?
Components of Switchgear. Switchgear essentially consists of switching and protecting devices such as switches, fuses, isolators, circuit breakers, protective relays, control panels, lightning arrestors, current transformers, potential transformers, auto reclosures, and various associated equipment.
What is low voltage switchgear?
Low Voltage Switchgear Switchgear for low voltage applications is generally rated up to 1000 V AC and 1500V DC.
