Answer / hasan mehdi

An alternator is an electromechanical device that converts
mechanical energy to electrical energy in the form of
alternating current. Most alternators use a rotating
magnetic field but linear alternators are occasionally used.

Answer / b soni

Alternating voltage may be generated by rotating a coil in
the magnetic field or by rotating a magnetic field within a
stationary coil. The value of the voltage generated depends
on-

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<
