Limitations of Traditional Analog Relays

Analog relays operate on the principle of comparing electrical quantities like current or voltage to predetermined thresholds. These relays typically utilize physical components like coils, levers, and contacts to perform their functions. While reliable, analog relays have several limitations:

  • Limited Functionality: Analog relays are designed for specific protection functions, such as overcurrent or overload protection. Implementing complex protection algorithms can be challenging with analog technology.
  • Slow Response Times: Analog relays rely on...
