A $22$ kV$/400$V $1$MVA Dy$11$ transformer is protected by an IDMTL overcurrent

$($OC$)$ relay with IEC standard inverse characteristic on the $22$ kV side. The

current transformer ratio is $75/1.$ The OC relay plug setting $($PS$)$ is $0\mathrm{.}75$ A and

time multiplier setting $($TMS$)$ is $0\mathrm{.}35.$

The transformer LV phase L$1$ cable developed an earth fault current of $10,000$

A$.$ Calculate the relay operating time. Which phase$($s$)$ showed trip indication?
