WebWhen a contact is open with the relay at rest, this is called Normally Open (NO), while if the contact is closed with the relay at rest the relay is Normally Closed (NC). NO relays are more common than NC relays. Non-latching (monostable) relays have only one stable position -- OFF, or unenergized position. Webrelays current elements the CT open circuit scheme can be used. The scheme works by opening the normally closed contacts and detecting the spike in voltage that should occur if the CT in that phase has primary current flowing. If the primary phase current is absent then no spike in voltage will Fig. 3. Open-phase detection scheme be detected. Webrelays current elements the CT open circuit scheme can be used.
