Gray color is of Gendalf The Gray from Lord of the Rings.
so it has magical properties, Gandelf himself painted the first transformer and enchanted it , no evil in filed can harm the transformer in Gray color, Optimus Prime ones asked help to Gendalf, then he decided to paint it with Gray Color.

Difference between on line capacitor and Station type capacitor
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<
