01 Protection VAMP 230, VAMP 255 and VAMP 257 Feeder and Motor manager series The protection relays of the VAMP Series are used for the selective protection of overhead line feeders, cable feeders, motor feeders, capacitor banks, reactors and busbars in power system distribution substations, power plants, industrial power systems, marine and offshore installations. Besides a comprehensive range of standard protection functions the VAMP series also offers bay control, measurement, primary circuit monitoring and communication functionality. main characteristics • omplete protection C Comprehensive selection of protection functions for distribution network overhead line feeders, cable feeders, motor feeders including large motors, capacitor banks and reactors. • otal control T Extensive bay control functionality including local and remote control of six objects and status supervision of another two objects. • omprehensive measurements C Wide range of measurement functions including phase-to-earth, phase-to-phase voltages, currents, frequency, active, reactive and apparent power, active and reactive energy imported and exported, power factor, negative phase sequence current, etc. • ower quality assessment P Power quality assessment and analysis including super­ ision of v harmonics up to the 15th order, THD as well as voltage swells and sags. • ault location F Integrated fault location with distance indication for short circuits in distribution networks irrespective of power network earthing system and earth-faults in compensated networks. • ltra-fast Arc flash protection U Unique integrated arc fault protection functionality for enhanced safety of switchgear, substations, people and property. • xtensive communication E Large number of supported communication protocols including IEC 60870-5-101, IEC 60870-5-103, Modbus TCP, Modbus RTU, Profibus DP, TCP/IP, SPA-bus slave, DNP3.0, DNP TCP, IEC 61850, Device Net or Ethernet /IP. • asy handling and management E Easy commissioning, configuration and operation of the relays supported by the straight-forward VAMPSET relay management software A unique feature of the VAMP relays is the arc fault protection system integrated into the relays. The extremely fast arc fault protection option adds a new dimension to the total safety of the installation and the reliability of the protection system. Further, VAMP relays incorporate power quality assessment based on fast Fourier transform and fault spot location based on fault reactance calculation. Customer specific configuration is obtained by freely configurable mimic display and logic programming by means of the easy-to-use VAMPSET software. After a network fault the relays support a subsequent fault analysis by providing event sequence recordings, fault value registration and disturbance recorder capability. Comprehensive functionality and communication makes VAMP an ideal choice throughout the world.

Quick selection table applications where reliable control and protection is needed. The features of the products vary in the number of digital inputs and outputs and in the number of analog measuring channels Power quality assessment The power quality of electrical networks has become increasingly important in modern society. Sophisticated loads, such as computers and automation systems, require an uninterrupted supply of "clean" electricity The VAMP feeder managers are provided with ntegrated power quality measuring and analysis functions, which help to reduce variations in the quality of the...

03 Protection VAMP 230, VAMP 255, VAMP 257 Fault location The feeder manager includes a sophisticated stand-alone fault location function. The algorithm used can accurately locate short-circuits in any type of distribution networks. The fault location is given as a reactance value, and the distance to the fault is also displayed on the local HMI, optionally as a mA signal and as a message over the communication system. The distance value can be exported, for example, as an event to a DMS (Distribution Management System). The system can then locate the fault. If a DMS is not available, the distance...

VAMP is a communication expert with a wide experience in interfacing with different system integrators' and SCADA suppliers' RTUs, PLCs, gateways etc. using different protocols. Flexible adaptation of the communication protocols together with powerful and easy to use software tools are the key of successful integration. VAMP protection relays and the VAMPSET tool provide access to practically any power system information you may need The VAMP feeder manager series feature three serial communication ports, two on the rear plate for connection to the plant control system and maintenance terminal...

VAMPSET setting and configuration tool VAMPSET is a user-friendly, free-of-charge relay management software for setting parameters and configuring VAMP relays. Via the VAMPSET software relay parameters, configurations and recorded relay data can be swapped between the operator's PC and the VAMP relays. Supporting the COMTRADE format VAMPSET also incorporates tools for analyzing relay events, waveforms and trends from data recorded by the relays, e.g. during a network fault situation Using a standard serial cable the PC running VAMPSET connects to the front or rear port of the VAMP relays. The...

Whether the time-grading or blocking based protection coordination principle is used, the traditional protection systems may not provide fast enough protection of substation faults. Further, high-impedance type of earth- faults may cause prolonged operation times of earth-fault relays leading to the significant release of the arcing energy. These facts pose a considerable risk to human beings and economical assets. By applying a modern, high- speed arc flash protection system the damage may be considerably reduced. Such an arc flash protection system is an optional feature that can be incorporated...
