circuits - Coggle Diagram
circuits
three phase AC circuits
line
currents
THROUGH ONE LINE (CONDUCTOR JOINING........)
voltages
VOLTAGE DIFFRENECE BETWEEN THE LINES
WHAT IS A LINE CONDUCTOR(WIRE) BETWEEN THE SOURCE AND THE LOAD
phase
current
THROUGH ANY ONE COMPONENT
LIKE ONE IMPEDANCE
voltages
VOLTAGE ACROSS ONE COMPONENT
ACROSS ONE IMPEDANCE
ACROSS ONE WINDING OR ONE SOURCE
types of connection
4 possibilities
caution while interconversion
sequence
sequnce in which voltages reach peak values
WHY NOT SIX
ONLT TWO
BECUASE CIRCULAR PERMUTAION
N-1 FACTORIAL NOT NFactorial
why positive and negative
how to differentiate between the two
HOW IN CASE OF DELTA CONNECTED SOURCES
THINK OF IF CONVERT INTO STAR FIRST AND THEN FIND VVab ......
short cut if ABC SDEQUENCE
VAB 1
VBC 2
VCA 3
REMEMBER THAT PHASORS ARE ROTATING
ABC
ABCABCABCABC.............
BCABCABCABCA.....
CABCAB.......
benefits
CONTANT INSTANTANEOUS power
LESS AMOUNT OF WIRE
PHASOR MAGNTIUDE EQUAL RMS
note that IAB is not the same as IBA
WHAT HAPPES WHEN MULTIPLY A PHASOR BY -1
IAB = VAB/ZAB
balanced
ampiltude frequncy and equal phase diffrence between any two
for load impedance is same
TIPS
ALWAYS BETTER TO DRAW THE DIAGRAM
MARK THE ASSUMED DIRECTIONS OF CURRENT AND VOLTAGES
calculation error reduce how
