In closed transition starting, what is the role of three current transformers (CTs) being used in the circuit?
What will be an ideal response?
The CTs reduce the current to a level that common overload heaters can be used to protect the motor.

Set up a system of equations that relate the mole fractions of Q, W, Y and Z in the mixture at equilibrium to the two equilibrium constants K1 and K2. You don’t have to solve the equations, but the number of equations and unknowns must be equal such that they could be solved. Assume a reference pressure of 1 bar.
The following pair of reactions is carried out in the gas phase:
Q+W ?Y
Q+Y ?Z
These compounds can be modeled using the virial equation at pressures of up to 15 bar:
And mixtures of the compounds can be modeled as an ideal solution of real gases.
A vessel initially contains 5 moles of Q and one mole of W, and the vessel is maintained at P=10 bar and T=700 K. The equilibrium constants of the reactions, K1 and K2, are both known at this temperature.
