Question

Pick value of protective relay is defined as​

Answer 1

Answer:

Pickup Value:

It is the minimum value of an actuating quantity at which relay starts operating, in most of the relays actuating quantity is current in the relay coil and pickup value of current is indicated along with the relay

Answer 2

• A protective relay is a relay device used in electrical engineering to trip a circuit breaker when a malfunction is detected.
• Protection cubicles for important  transmission lines and generators have many discrete electromechanical devices or one or two microprocessor relays.We say a relay "picks up"  when it opens or closes a "b" or "a" contact, and the "pickup"value is the least value of the actuating amount that will produce such  an operation when the quantity is gradually increased from zero.
• Relay Power Consumption - The amount of power consumed by the relay circuit at the rated current or voltage, measured in VA for AC and watts for DC.  
• Pick Up ;When a relay moves from the off to the on position,it is said to pick up, and the activity of the relay is referred to as relay pick-up.
