Does relay protection require both DC and AC power
The relay contacts often have AC and DC ratings for current and voltage. For an AC relay, you need an AC coil, and for a DC relay. What protection is most suitable for a relay circuit with an unspecified load (DC coil, AC load)? What measures can be taken to protect the relay itself and handle electrical surges and spikes in an industrial environment? Typically, I place a flyback diode on the coil to prevent back EMF. A DC relay coil requires DC power to operate. This guide demystifies the six fundamental differences between AC and DC power relays, providing a clear framework to ensure you select the right component for optimal performance, safety, and longevity in your specific application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. While this is bad, It's not a.
