The positive sequence component of the voltage at the point of fault in a power system is zero for a _________fault.

The inductance and capacitance of a power system network upto a circuit breaker location are $$1H$$ and $$0.01$$ $$\mu F$$ respectively, the value of the shunt resistor across the circuit breaker, required for critical damping of the restriking voltage is
