VAMP protection relays include all the main features you are used to seeing in the medium voltage distribution protection systems. They also include a number of other innovative and unique features.

Basic features

• Comprehensive and versatile setting and programming.

• Programmable blocking and output matrix.

• Disturbance recorder and evaluation software.

• Availability of several communication protocols in the relays.

• Continuous self-supervision.

• Robust metal enclosure.

• Wide auxiliary supply voltage range.

Unique features

• All over-current relays can be equipped with arc flash sensors. The sensors are installed, for instance, in the cable compartment of the outgoing feeders.

• Thanks to optional integrated transducers, any measured and calculated values can be freely connected to the mA outputs.

• Maximum demand measurement quantities and disturbance recorders are available for load profiling and fault evaluation.
