Answer Posted / eee
surge arrestor: these are capacitive/ solid state devices
which prevents sudden rise in voltage (max 2Vrated)
lightning arrestors: these are nonlinear elements, provides
high impedance in normal working, very low impedance at very
high voltage (lightning)....
withgap metal oxide will have higher voltage carrying
capacity. then the without gap MO.....

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<
