AC three phase

the order phase voltages reach their maximum is

• phase rotation

• phase order

• phase sequence

• phase shift

what colours represent our three phases and in what order

(a)  

how many electrical degrees are phases displaced

• 30

• 60

• 90

• 120

what is an advantage over a three phase system to a single phase

(a)  

does a phasor represnt RMS values or max values

• max

• RMS

what direction does a phasor and consequently the correct phase sequence of a machine rotate

• anticlockwise

• clockwise

australian distribution system is

• 3 phase

• single phase

AS3000 standards three phase voltage is

(a)  

how can we connect three phases

• star

• mesh

• delta

• y
