 Static relays

 

Advantages of static relays

 

  Due to the amplification of energizing signals obtainable, the sources need only provide low power. Therefore the size of the associated current and voltage transformers could be reduced.

 

 Improved accuracy and selectivity.

 

 Fast operation of relays and hence fast clearance of faults.

 

 Flexibility of circuitry would allow new and improved characteristics.


Basic circuits employed

 

 Timers

 

 Phase comparators

 

 Amplitude Comparator

 

 Level detectors

 

 Integrators

 

 Polarity detectors

 

High reliability operational amplifiers are used for realizing the basic components of static relays.
