Answer Posted / anand shukla
a relay is a sensing device ,which sense the fault and give
signal to the circuit breaker.
relay are many types which is is used in different
conditions.
1- electromagnetic relay
2- thermal overload relay
3-directional & nondirectiobal relay.
4- distance relay
5-mho relay
6-trip circuit supervision relay
7- master trip relay.
in realy some types of contacts are fitted
like no and nc which is interchange when current exceed a
preset value it means when relay operated.

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
