The Gauss Seidel load flow method has following disadvantages. Tick the incorrect student.

In a biased differential relay the bias is defined as a ratio of

Keeping in view the cost and overall effectiveness, the following circuit breaker is best suited for capacitor bank switching

A generator feeds power to an infinite bus through a double circuit transmission line. A 3 phase fault occurs at the middle point of one of the lines. The infinite bus voltage is 1 pu, the transient internal voltage of the generator is 1.1 pu and the equivalent transfer admittance during fault is 0.8 pu. The 100 MVA generator has an inertia constant of $$5$$ MJ/MVA and it was delivering 1.0 pu power prior of the fault with rotor power angle of $${30^ \circ }\,\,$$. The system frequency is 50Hz.

The initial accelerating power (in pu) will be
