What type of protective system we uses in L.V. distribution panels?..

Answer / jagadisha.n bmsit

Different protection systems which is used in LV panels are:
1. Short circuit protection :- It is done by choosing set
point in sc protection relay which is present inside the CB's.

2. Thermal protection for Busbars/ cables:- Bec extreme
thermal point cause flash over

3. Over current protection

4.Protection provided by proper shielding & interlocks such
that operator & maintenance people can not accesses live parts
