Application
The PROTEC Z family is a range of surge suppressors for protection of medium voltage motors, generators and transformers against transient switching surges. PROTEC Z surge suppressors alter circuit parameters in such a way that transient over voltages due to switching are suppressed so as to maintain the voltage at the machine terminals within the IEEE ratings. They are recommended for use in systems incorporating vacuum, SF6 and metal vapour contactors and breakers. PROTEC Z surge suppressors are supplied in compact and standard versions for MV applications.
