Answer / ankit

Actually you are confused in the ratings:
A CT i.e. current transformer is used as an instrument
transformer to measure current.

And Similarly PT i.e. Potential Transformer is used for
voltage measurement.

The ratings specified by u are the nominal ratings of a big
building like Mall, IT park so the transformer is A
DISTRIBUTION X-MER which is used for meeting the load
requirements of that premise.

Answer / manju & raju

Generally used for distribution Transformer.
CT-used for current measuring purpose.
PT-used for voltage measuring purpose.

Answer / pawan dahiya

CT is current transformer and used in high current
PT is Potential Transformer and used in high voltage

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<
