LV MV HV SWITCH GEARS:
Switchgears are classified based on their voltage level. As a result, there are three major types of switchgear:
High voltage (H.V.) switchgear
Medium voltage (MV) switchgear
Low voltage (LV) switchgear
LV SWITCHGEARS:
Low voltage switchgear refers to electrical switchgear that is rated to 1kv. Thus, the term LV switchgear collectively refers to H.R.C. fuses, low voltage circuit breakers, offload electrical isolators, switches, earth leakage circuit breakers, molded case circuit breakers (MCCB) and miniature circuit breakers (M.C.B.). That is, all accessories that are required in protecting the LV system. The LV switchgear is mainly used in the LV distribution board. The system is made up of the following parts:
Incomer
Sub-incomer
Feeders
MV SWITCHGEARS:
Medium voltage switchgear is a switchgear system that can handle voltages ranging from 3kv to 36kv. These are available in a variety of styles, including metal-enclosed outdoor types, metal-enclosed indoor types, and outdoor types without metal enclosures, among others.
Medium voltage switchgear should be able to perform the following functions:
Switching capacitive currents
Switching the inductive currents
Performing normal ON/OFF switching
Other special applications
HV SWITCHGEARS:
High voltage switchgear is a power system that deals with voltages more than 36 kV. The arcing created during switching operation is likewise very high due to the high voltage level. As a result, more caution should be exercised while constructing high-voltage switchgear.
