wat s the difference between diode and capacitor
Answer Posted / mahalakshmi mohan
The difference between a semiconductor diode and a
capacitor can be explained with the following example:
In an ac circuit, if you connect a capacitor between the
input and the output terminals, it charges upto its maximum
value in the first half cycle of the ac waveform, then
discharges and recharges with opposite polarity in the
negative half cycle of the waveform. Thus, a capacitor acts
as a short circuit for both the cycles of an ac waveform.
But, if you connect a p-n junction diode in a circuit, it
will be forward biased (and hence act as a short circuit)
for one half-cycle. It will act as an open circuit for the
other half-cycle when it becomes revverse biased due to
which it will act as an open circuit.

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<
