  • Page 4: General

    The VAMP 55 protection relay concept has two alternative casing layout designs: basic and slim fit. The VAMP 55S includes more compact casing than in the basic design. In the VAMP 55S, the same protection, measurement and control functions and communication interfaces are supported as in the basic 55 relays.

  • Page 88: Voltage Sags And Swells

    One of the most important power quality functions are voltage sag and swell monitoring. VAMP provides separate monitoring logs for sags and swells. The voltage log is trigged, if any voltage input either goes under the sag limit (U<) or exceeds the swell limit (U>). There are four registers for both sags and swells in the fault log.
