where they are using surge arrester and lighting arrester?
how they connect? what is the purpose of that?

Answer Posted / gopal agarwal

SURGE arresters are used for arresting i.e. controling
lightining surgs which are accured during clouding.these
lightining surges are of very high voltage ranges such as
many times greater than the rating of equipments ,which will
damage them and hence these are used at both sides end of
electrical equipments for protection.

When we use air circuit breaker, it has O/L protection ,time delay SC protection, Instataneous SC protection & ground fault protection. They all have some setting range. But what is the suitable/allowable setting for the above protection which will be safe for the equipment? For example-O/L protection setting have a range of (0.4,0.45,0.5,0.55,0.6,0.65,0.7,0.8,0.9,1.0)xIn Time delay SC protection have a range of (1.25,1.5,2,3,4,6,8,10,12)xIn Time delay setting is 0.02,0.1,0.2,0.3,0.4 Instataneous setting is fixed to 20xIn Gound fault setting is given 100A,300A,600A,900A,1200A This setting are for 2500A ACB. So what will be the basic allowable setting for the above protection? is there any formulae to calculate this<
