Used in this context, 'R' probably stands stands for 'red'. This is one of three colours used to identify the lines(not phases) of a three-phase system. The other two lines are coloured according to the standards used in your country. In the UK, for example, the colours are red, yellow, and blue -which also represent the positive phase sequence of the three-phase supply. Other methods of identifying lines include letters, e.g. 'A-B-C', numbers, e.g. '1-2-3', combinations of the two, e.g. 'L1-L2-L3', or other colours, e.g. 'brown-black-grey'.
'R' could also represent one of the letters, 'R-S-T', which has been used in Germany to represent the three lines of a three-phase system.

Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
What is a RC phase shifter ciRCuit?
R resistor C capacitance will shift phase since the capacitor will take time to charge.
What is the difference between positive sequence and negative sequence arrangement?
The order in which the voltage of the coil reaches to the maximum value is called the Phase Sequence.POSITIVE PHASE SEQUENCE: If the coil is rotated in anticlockwise direction, the phase sequence will be Positive Phase Sequence, i.e., R-Y-B or A-B-C.NEGATIVE PHASE SEQUENCE: If the coil is rotated in clockwise direction, the phase sequence is called Negative Phase Sequence, i.e., R-B-Y or A-C-B.NOTE: Phase Sequence is of great importance in parallel operation of three phase transformers and alternators.

Why Y phase is high in YNyn0 when doing magnetic balance test?
because y phase is y phase ...it is not b phase or R phase so it is high

How do you reverse a direction of a slip ring motor?
It is very simple. Just interchange any two phase wires. i.e. Y and B ( or ) R and B ( or ) R and Y for example Stop the supply. keep R phase wire as it is and disconnect B phase wire and Y phase wire. Connect B phase wire to the Y phase motor stud and Y phase wire to the B phase motor stud. Now give the supply, now motor revolves in opposite direction to the earlier.
