Schneider Vamp 55 Protection Relays

Schneider VAMP 50 relay series offers a comprehensive selection of modular protection relays for overcurrent, earth fault, voltage, frequency ay and line differential protection. Models available: Schneider VAMP 50 relay, Schneider VAMP 52 relay, Schneider VAMP 55 relay, Schneider VAMP 59 relay

Protection for LV and MV feeders and motors

Schneider Electric?s VAMP 50 series product range is highly flexible and meets the protection and control needs of a number of power systems, from simple overcurrent, to busbar voltage or line differential applications. Featuring native IEC 61850 and VAMP?s unique arc flash protection, the VAMP 50 series is designed around proven technology concepts and developed in close cooperation with customers, making it both reliable and modern. VAMP 50 series also introduces a complete set of measurement functions including line and residual currents, current imbalance, system frequency and harmonics, replacing conventional metering functions in switchgear and controlgear installations. User-friendliness is a designed-in feature of VAMP products and the VAMP 50 series is no exception with a large LCD display, programmable function keys and easy-to-use VAMPSET software.

Main features of Schneider VAMP 55 relay

• Fully digital signal handling with microprocessor technology, and high measuring accuracy on all the setting ranges due to an accurate A/D conversion technique.
• Set of functions for voltage and frequency based protection of lines, generators and transformers
• The device can be matched to the requirements of the application by disabling the functions that are not needed.
• Flexible control and blocking possibilities due to digital signal control inputs (DI) and outputs (DO).
• Easy adaptability of the device to various substations and alarm systems due to flexible signal-grouping matrix in the device.
• Possibility to control objects (e.g. circuit-breakers, disconnectors) from relay HMI or SCADA/automation system
• Freely configurable large display with six measurement values.
• Freely configurable interlocking schemes with basic logic functions.
• Recording of events and fault values into an event register from which the data can be read via relay HMI or by means of a PC based VAMPSET user interface.
• All events, indications, parameters and waveforms are in non-volatile memory.
• Easy configuration, parameterisation and reading of information via local HMI, or with a VAMPSET user interface.
• Easy connection to various automation systems due to several available communication protocols. Native IEC61850 implementation is available as option.
• Flexible communication option concept available to support different media requirements (serial interfaces, optical fibres, Ethernet etc),
• Built-in, self-regulating ac/dc converter for auxiliary power supply from any source within the range from 40 to 265 Vdc or Vac. The alternative power supply is for 18 to 36 Vdc.
