APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The Three-Phase Over Current Relay is a protective relay that is sensitive to overcurrent conditions in three-phase power systems. It trips when the current in any one of the three phases exceeds the current setpoint. Current setpoint and time delay adjustments are provided along with two sets of contacts.

Detailed explanation-2: -Used to ensure the sequence is correct when connecting 3 phase loads. With an incorrect phase sequence the relay will start to de-energise, preventing the starting of incorrectly connected machinery. The relay will also trip if there is a phase loss and can therefore be used as a phase failure relay.

Detailed explanation-3: -A phase failure relay which is also known as phase protection relay prevents three-phase motor failure due to line or motor overheating. The relays are designed to protect the devices with sensitive operation voltage against failures due to line voltage.

Detailed explanation-4: -Delta 3-Phase EMI Filters are designed to reduce the electromagnetic interference in devices connected to 3-phase delta power. The Delta configuration contains four wires; three hot conductors and one ground conductor.
