Vamp feeder managers and protection relays are used for
feeder, bus bar, power and distribution transformer, capacitor bank and for
secondary power distribution station applications.
The feeder managers were developed for the utility segment, where extensive
protection, auto-reclosing schemes, control, measurement, disturbance recording,
event tracking, power quality assessment, and fault location are required in a
single unit. Protection characteristics support definite time, IEC and IEEE
inverse characteristics. In addition, the feeder manager has programmable curves
for those applications where standard curves are not suitable.
Vamp feeder managers are used as an interface for primary processes in either
local or remote operations. Various communication protocols such as native IEC
61850, SPA, IEC 60870-5-101, IEC 60870-5-103, DNP 3.0 enable connection of Vamp
feeder managers to alternative control systems.

Vamp protection relays differ from the feeder managers with
respect to mechanical size, number of analogue inputs and digital inputs /
output contacts. The feeder protection relays as such are used for applications
where local / remote control is not required.
Arc flash protection is optional with Vamp's feeder managers
and protection relays.
Switchgear protection is used with the Vamp arc flash
protection system. As the technology leader, Vamp offers selective arc flash
protection systems for every need. Both fibre and point sensor technologies are
supported for arc flash detection. Arc eliminators can be used together with arc
flash protection systems for extremely fast extinguishing of arc flashes.
