MULTIPLE CHOICE QUESTIONS 1. As compared to an electromagnetic overcurrent relay, the following is not a feature of a static overcurrent relay. (a) low burden (b) no moving parts (c) fast response (d) more transient over-reach 2. The component used to achieve time delay according to inverse time overcurrent characteristic in a static relay is (c) R-C circuit (d) integrator (b) a two-input phase comparator (d) either (b) or (c) (a) differentiator (b) comparator 3. The static distance relay can be achieved by using (a) a level detector (c) a two-input amplitude comparator 4. As compared to the numerical relays, static relays do not have the feature of (a) low burden (b) no moving parts (c) flexibility due to programming approach (d) miniaturisation 5. The component used in the output circuit of a static relay is (b) comparator (a) opamp (c) capacitor (d) thyristor MULTIPLE CHOICE QUESTIONS 1.
