VAMP 300 Series
Protection and Control managers for MV power systems
The VAMP 300 series offers a comprehensive family of protection and control devices with versatile measurement functions for the management of feeders, motors, generators and transformers.

VAMP 300F: Applications where reliable control and protection is needed for feeders including overhead lines, cables and busbars in power system distribution substations, power plants, industrial power systems, and marine and offshore installations.

VAMP 300M: Applications where advanced control and protection is needed for motors and motor feeding cables. Optional RTD interface units enable use of temperature measurements from motor bearings and windings for accurate thermal protection, mimic display viewing and transfer of temperature information to the automation system.

VAMP 300G: Applications where differential protection of generators, protection of generator block transformers or overall generator protection is required. The VAMP 300G is optimal with medium-sized generators up to 150 MW. The external RTD module increases knowledge and accuracy in generator management.

VAMP 300T: Applications with two-winding power transformers where differential, short circuit, thermal overload, earth-fault and voltage protection is required.
