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.

What does A three phase load requires a minimum of?
Yes, the minimum is three wires, usually used when the three phases are in balance, with equal currents in all three lines. In conditions when the three phases might be unbalanced, a neutral wire is added, which makes it a 3-phase 4-wire system, and the current in the neutral depends on how out-of-balance the currents in the three lines are.
Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?
In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.
Core balance current transformer?
whats a core balance current transformer? Core Balance CTs are special CTs used to detect Earth faults & usually used for Restricted Earth Fault Protection. It is a ring type CT through which the cables carrying current of all the three phases (R,Y & B) are passed through. (In a 3phase 3 wire system) Under normal operating conditions, summation of current through the three phases shall be equal to zero. In event of a fault, the summation of the current shall no longer remain zero (zero sequence current shall flow during earth fault) & thus the fault can be detected.
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
What are the three important phases in the manufacturing process?
3 phases in manufacturing process

You switched leads on your 3phase motor and it did not reverse?
Then it is not a three phase motor.
What is tcp session?
A TCP session is a data transfer that takes place using the transmission control protocol. A session has three phases, connection establishment, data transmission, and connection termination.
Why the number of phases are limited only to three why not five or six?
Physical phases of matter are not limited to three. Phases of the moon are not limited to three. Phases of a wave form are not limited to three. What phase is limited to three?
What is the Max amp rating for 3phase dc motor?

What are the three phases of drug effects?
There are three phases of drug effects. These three phases are the administration phase, active phase, and the metabolism phase.
What phases does Empyema have?
Its development can be divided into three phases
Angle between three phases?
The generated angle between phases in a three phase system is 120 degrees.
What are the 3 phases of mater?

The three phases that make up interphase are G1, S, and G2.
