What is a Phase Loss? How can I protect my equipment?

Tuesday: September 17, 2019 : Three-Phase Monitor Relays

When one phase of a three-phase system is lost, a phase loss occurs. This is also called 'single phasing'. What causes a phase loss? How can this condition be monitored and equipment failure and downtime be prevented?
