Removable / interchangeable communication modules for connecting the relay to various system communication solutions and medias 2

3 Arc protection 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 protection system the damage may be considerably reduced. Such an arc protection system is an optional feature incorporat-able in all current measuring VAMP relays. The VAMP relays measure the fault current. If the arc protection option is selected the relays also measure light via arc sensor channels monitoring the whole switchgear. Should an arcing fault occur in the switchgear the arc protection system provides an extremely fast tripping of the circuit breaker. The fault will be prevented from spreading and quickly isolated, which may save human lives and valuable economical assets. Communication The Vamp 259 line manager can be equipped with in-built Ethernet interface which can be used for either ModbusTCP, Dnp 3. over TCP and IEC 6185 communication. The 6185 protocol can be used to read or write static or to receive events sent spontaneously from the relay. In addition, the interface allows peer-to-peer communication between the relays - this is Goose communication. The 6185 interface is configured with familiar, user-friendly Vampset software. The 6185 data model, data-sets, report control blocks and the Goose communication are configured according to the requirements of the system configuration. Vampset is also used to produce ICD files, which may be needed for the substation RTU configuration. The IEC 6185 slution is a native implementation which means that the IEC 6185 functionality is embedded in the software. Software requires only the main CPU of the relay no additional processor or gateway module is needed. SCADA, DCS or SA system Maintenance Terminal The VAMP relays are easily interfaced with any renowned and recognized SCADA system Control and status of the process Events Measurements Fault location Time synchronizing using GPS Relay settings, configuration Fault and disturbance analysis Power quality monitoring Primary equipment condition monitoring Time synchronizing using GPS IEC , IEC , Modbus RTU, Modbus TCP, Profibus, SPA, DNP 3., DNP TCP or IEC 6185 Traditional protection relay systems do not provide fast enough protection in an arcfault situations.

4 Line Manager VAMP 259 Line distance protection The distance protection function calculates the impedance Z = U/I for each of the distance element. If impedance is inside the tripping zone (normally presented in R-X plane), the distance function operates. For short circuit protection in the relay are 15 independent distance elements as well as for the earth fault protection. The distance protection function calculates impedances in each of the fault loop continuously thus giving the distance protection high precision and accuracy for demanding sub-transmission applications. The distance protection s zones implement polygonal characteristics. Additionally the function supports load blocking area (i.e. load encroachment area) settings which are possible to enable for each zone individually. See figure 3 for details. VAMP 259 distance protection is applicable for power systems where the grounding (earthing) star point can be solid or low resistance grounded. Resonant-earthed via Petersen coil or isolated can be protected with sensitive directional earth fault protection. The distance protection tripping can operate with or without the use of tele protection schemes. If e.g. POTT (permissive underreaching zone transfer trip) or PUTT (permissive overreaching zone transfer trip) is required it can be achieved via any DI/DO signals or pilot channel communication (85). At least one DI/DO pair is required per direction Xset Tripping Zone Z Z Rset Rset -4 Xset -5 An example of a tripping zone presented in RX-plane Typical application 3 VAMP ,85,87L 25,27,59,79 67/67N 5/51,5/51N Pilot channel communication Cable or overhead line 1 X 8 6 5,98 4,98 Zone3 Zone5 Line Zone1 Zone2 Zone3 Zone4 Zone5 1,25,75 X 4 3,98 Zone2 Zone1 2 R ,25 R ,7 2,2 2,7 3,2 3,7 4,2 4, ,98 -,25 Load angle setting Zone4-6 -, The distance protection application polygonal characteristics.

5 Line differential protection Line differential protection di> / 87L provides high speed clearing for faults occurring at any point on a protected area of the transmission line or cable. The line differential protection unit uses voltage measurements to calculate the resistive part of each of the three phase currents. The dedicated communication channel, called pilot channel, is used between two relays to exchange information on resistive phase currents and to determine whether the fault is internal or external to the protected area.
