A type of diode that permits current not only in the forward direction like a normal diode, but also in the reverse direction if the voltage is larger than the breakdown voltage known as "Zener knee voltage" or "Zener voltage".
A special diode designed to operate in the reverse bias breakdown region. A zener is designed to break down at a specific value of reverse bias voltage.
The rating of a zener diode; equal to the value of reverse bias voltage at which breakdown occurs.
A synthetically produced substance with a porous, crystalline structure; a major component of a type of catalyst used in many fluid cat cracking units.
Manual tuning methods, open loop and closed loop, that provide approximate tuning parameters
Zonation is the creation of zones in a logged interval of a well.
The protection provided by a distance relay for approximately 90% of a transmission line section
A zone of backup fault protection provided by a distance relay that covers a line section beyond Zone 1
A zone of backup fault protection provided by a distance relay that covers a line section beyond Zone 2
