Given we have a $87$T differential we want to set the harmonic restraints to over come the magnetizing inrush and the overexcitation of the transformer.

What relay setting should we use for each and what is the function of each harmonic restraint??

$2$nd order harmonic restraint is for $[$ Select $]["$magnetizing inrush current", "overexcitation", "nothing, trick question"$]$ set to $[$ Select $]["25\%","15\%",$ "trick question", $"0\%","35\%","45\%"]$

$3$rd order harmonic restraint is for $[$ Select $]["$nothing$,$ trick question", "overexcitation", "magnetizing inrush current"$]$ set to $[$ Select $]["35\%","45\%","0\%","15\%",$ "trick question", $"25\%"]$

$4$th order harmonic restraint is for $[$ Select $]["$nothing$,$ trick question", "overexcitation", "magnetizing inrush current"$]$ set to $[$ Select $]["0\%","15\%",$ "trick question", $"25\%","45\%","35\%"]$

$5$th order harmonic restraint is for $[$ Select $]["$magnetizing inrush current", "nothing, trick question", "overexcitation"$]$ set to $[$ Select $]["0\%","15\%","25\%",$ "trick question", $"45\%","35\%"]$

Note: one of these could be a trick question $($i$.$e$.$ this setting does not exist!$)$
