First of all, the colours red, yellow, and blue, are applied to LINES not to phases!

To determine which line is which, you must compare them with lines that are identified. This process is known as 'phasing out', and is difficult to explain without using a diagram. I suggest you check out 'phasing out' on the internet.

What will happen if two different rating of Transformers RYB of the secondary winding side is connected with the RYB of the another transformer?

It isn't a good idea to connect transformers in parallel unless they are identical transformers. If they are not exactly the same model there is a danger of high circulating currents, which could cause them to overheat.


What if in 3-phase connection load is not balance in three phases ie RYB?

due to unbalance load 1. Due to negetive phase sequence components in current generator and transformers suppling the load will be over heated 2. The opposite torque on the shaft will damage, rotors are more likely to damage. 3. High current through neutral of the system, normally neutral cable conductor is of lesser size then phase and hence it may be damaged.


Why you indicate RYB for three phases?

R-Y-B is a British standard designation, similar to A-B-C in the Americas.AnswerThe letters, R-Y-B, stand for 'red-yellow-blue', which were the standard colours used to identify the line (not 'phase') conductors of a three-phase power supply in the United Kingdom until the introduction of the EU standard, 'brown-black-grey'. The obvious drawback with the EU colour code is that the corresponding letters, 'B-B-G', are not much use for labelling line conductors in schematic diagrams!In practise, the colours red-yellow-blue continue to be used throughout the British transmission and distribution system, whereas the colours brown-black-grey are now mandatory for low-voltage installations such as residences, etc.The letter sequence, R-Y-B, corresponds to the normal phase sequence for a three-phase system.


What is ryb in electrical?

The letters, 'r-y-b', represent the colours 'red-yellow-blue', which are used to identify each of the three lines of a three-phase system. This remains the current UK standard for electricity transmission/distribution systems, although for residential/commercial wiring, the EU colours 'brown-black-grey' have been adopted.Alternatives include 'r-s-t', 'a-b-c', '1-2-3', etc.


Can you Show diagram of 3 phase motor circuit?

Connect the three wires that come out of the motor to the three supply wires that come from the magnetic contactor. Turn the power on and push the start button. If the motor turns the wrong way, shut the power off and change any two wires in the motor junction box.

What is the difference between three phase load and phase supply?

How much current equipments are drawing from three phases (combined or individual) is called three phase load and how much supply we are getting from source is called three phase supply. Ex. In INDIA single phase supply is 220 volt ac with neutral. So in three phase supply all RYB phases should be 220 volts ac with neutral individually. If we calculate with phase to phase than it shoulb be 415 volts ac.

What color does red and green light make?

Green light + red light in red, green, blue context makes yellow; in red, yellow, blue context, it makes white. RGB is used for computer screens, and RYB for reflected light such as from paintings.


What color is yellow?

YELLOW!!!!............................................very light tintVery Intelligent Answers - Real Answer: What color is YellowYellow is the color evoked by light that stimulates both the L and M (long and medium wavelength) cone cells of the retina about equally, but does not significantly stimulate the S (short-wavelength) cone cells; that is, light with much red and green but not very much blue. Light with a wavelength of 570-580 nm is yellow, as is light with a suitable mixture of somewhat longer and shorter wavelengths. Yellow's traditional RYB complementary color is purple, violet or indigo. Yellow's colorimetrically defined complementary color in both RGB and CMYK color spaces is blue.
