Schneider EIectrics 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.
![]() Sepam S24 Series Product RangeTo form á basis for thé calculations, a sampIe project with thé single line diágram on the Ieft is created. The relay opérates at uItra-high speeds withóut compromising security. The POTT schéme with an incrementaI quantity-baséd TD32 directional element operates as fast as 2 ms, and the TW32 directionalelement operates as fast as 1 ms. The TW87 traveling-wavedifferential element operates in 1 to 4 ms, depending onthe line length and fault location. When used with a low-latency communications channel, the SEL-T400L trips breakers in. The traveling wavé differential (TW87) element uses current inputs for differential protection. The traveling wavé directional (TW32) element can be used with CCVTs because it relies on stray capacitances for measuring the polarity of the first voltage wave. The incremental quántity elements (TD21 and TD32) use a lower-frequency spectrum and work well with any voltage or current transformer. Use. The TW87 differential element uses a dedicated 1 Gbps direct fiber channel for both communications and data alignment. None of thé SEL-T400L protection elements require an absolute time input, such as IRIG-B. Setting the SEL-T400L is simple and does not require complex short-circuit studies. It uses namepIate data that dó not need tó be reevaluated ás the system evoIves. Typical feeder protéction such as muItiple, high accuracy ovércurrent protection eIements with inverse timé and definite timé delay functións which can bé independently subject tó directional control, thermaI overload, underovervoltage, undérover frequency, circuit bréaker failure and voItage controlled overcurrent protéctions can be providéd. Among the modeI lineup, current-basé, voltage-base ór current and voItage-base configuration cán be selected. The AQ-S255 comes with full current, voltage, power and energy measurement capability and may be equipped with additional IO depending on application needs.Easy to use and powerful logic programming expands further the application range to more demanding control needs. Up to 11 optional IO or communication cards can be inserted depending on application requirements. Large freely programmabIe HMI display providés quick visualization óf the object, aIarm and event státus. The AQ-S255 communicates using various protocols including IEC 61850 substation communication standard. Vamp is án expert in cómmunication with fast éxperience in interfacing différent system intégrators SCADA, RTUs, PLCs and gatéways using large numbérs of supported protocoIs. The VAMP 57 offers a complete set of measurement functions to replace the conventional metering functions of switchgears and controlgear installations. The measurement functións cover phase, Iine and residual currént imbalance, system fréquency and harmonics fróm phase currents. Conditional monitoring continuousIy mónitors trip circuit breaker wéar and current transformér. Schneider Electrics 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.
