Answer Posted / vivek gupta
power factor is the cosine angle betweem voltage &
current,In my view current charges inductor coil during
induction through reactive power,so we provide capacitive
power to maintain power factor ,during this process voltage
charges capacitor so current again lead voltage and we got
good power factor .
P=VICOS (PI),WHERE VOLTAGE &POWER IS CONSTT.
IT MEANS CURRNT IS DIRECTLY RELATED TO COS(PHI)
IT MAEANS IF COS PI DEC. ,THEN CURRENT WILL INCREASE
THAT IS HARMFULL FOR OUR GEN WDG

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<
