Advantages of static relay over electromagnetic relay?

Advantages of static relay over electromagnetic relay

  • No moving contacts; hence associated problems of arcing, contact bounce, erosion, replacement of contacts

  • Low power consumption as low as 1mW

  • No gravity effect on operation of static relays. Hence can be used in vessels ie, ships, aircrafts etc.

  • A single relay can perform several functions like over current, under voltage, single phasing protection by incorporating respective functional blocks. This is not possible in electromagnetic relays

  • Static relay is compact

  • Superior operating characteristics and accuracy

  • Static relay can think , programmable operation is possible with static relay

  • Effect of vibration is nil, hence can be used in earthquake-prone areas o Simplified testing and servicing. Can convert even non-electrical quantities to electrical in conjunction with transducers.
