Why high Voltages come in multiple of 11, like 11 KV, 33KV,
66 KV, 132 KV etc.
Answer Posted / bhanu prakash
ac voltage of the system is measure in rms voltages,
so rms voltage= avg. voltage * form factor.
form factor of sinusoidal voltage is 1.11
since every avg. voltage multiplied by factor 1.11, high
voltage come in multiple of 11 only

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<
