In digital relay, relay dependability is the ratio of (Number of correct trips)/(Number of desired trips+Number of incorrect trips) (Number of correct trips)/(Number of desired trips) (Number of correct trips)/(Total number of trips) None of the above

Choose the correct option from the following statements: 1- ........................................ to leave all healthy circuits intact to ensure continuity of supply. (Sensitivity - Selectivity - Stability) 2- is faults in power systems with more than 80% of the occurring faults is (Temporary Faults- Permanent Faults - none of them) 3- .... is based relays are specifically used to calculate algorithm numerically(Solid state relay - Numerical relay - Electromechanical relay) iv. 4- ............ is the most widely used in over-current relay (Inverse definite minim time - Definite time - none of them) 5- ............ fuse where expulsion gases causes no problem (Vacuum-Expulsion - none of them)
