What does substation
operator do in
substation?
Answer Posted / me
A Substation Operator’s job is to inspect, operate, and
maintain electrical substations, which contain equipment
that transforms electricity from one voltage to another so
that it can be safely used by customers.
another way: An electrical grid is like a relay race. The
starting line is the power plant and the finish line is the
customer’s home or business. In between, the baton —
electricity — is passed between hands several times, which
helps it travel farther, faster.

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<
