The compact solution HSBT 7VU683 is designed to fit for the primary diagrams of single busbar (2 CBs) and segmented single busbar (3 CBs). It has incorporated the traditional HSBT philosophy. Additionally, the unique Real Time Fast Transfer mode helps to improve the efficiency.Permanent availability of electricity is essential for the reliable production of a great number of processes in power stations and industrial plants where lots of inductive motors are installed. To achieve this, a busbar is normally equipped with two or more independent incoming power sources to provide the possibility to switch to standby source in case of main source interruption or failure.The power supply interruption with tens of millisecond has a small impact on rotating loads. Thus, the High-Speed Busbar Transfer (HSBT) device helps to control and monitor the progress to ensure the fast but reliable switching-over. It can be initiated manually or automatically.Based on the existing worldwide used SIPROTEC 4 platform, the reliability, stability, and efficiency of HSBT 7VU683 are guaranteed. Thanks to its powerful and flexible performance, multi-functions are integrated into one system, e.g, power supply transfer, relay protection, and supervision.The integrated protective functions are to protect the tie-CB in segmented single busbar diagram against short-circuit and ground fault. The integrated supervision functions are to monitor the voltage phase sequence and voltage secondary circuit, then gives out an alarm in case of failure.The integrated programmable logic (CFC) allows the users to implement their own functions. The flexible communication interfaces are open for modern communication architectures with the control system.

The 7VE61 and 7VE63 paralleling devices of the SIPROTEC 4 family are multifunctional compact units used for paralleling power systems and generators.Their technical design ensures highly reliable paralleling due to their 1-channel or 2-channel measurement method and their hardware design. This is supported by numerous monitoring functions. The units automatically detect the operating conditions. The response to these conditions depends on settings. In synchronous network switching mode, the frequency difference is measured with great accuracy. If the frequency difference is almost zero for a long enough time, the networks are already synchronous and a larger making angle is permissible.If the conditions are asynchronous, as is the case when synchronizing generators, the generator speed is automatically matched to the system frequency and the generator voltage to the system voltage. The connection is then made at the synchronous point, allowing for circuit-breaker make-time.The 7VE61 paralleling device is a 1-channel unit (paralleling function + synchro-check) for use with small to medium-size generators and power systems. It is more reliable than 1-channel paralleling devices. It can also be used for synchro-check, with parallel operation of three synchronization points.For larger generators and power systems withhigh reliability requirements, the 2-channel 7VE63 is recommended. Two independent methods decide on the connection conditions. The unit also has the full control functions of the SIPROTEC 4 family.Voltage and frequency functions including voltage vector jump (??) are optionally available for protection or network decoupling applications.The integrated programmable logic functions (continuous function chart CFC) offer the user a high flexibility so that adjustments can easily be made to the varying requirements on the basis of special system conditions.The flexible communication interfaces are open to modern communication architectures with control systems.

The guardian for your overhead line networks (3.3 to 66 kV 50/60Hz) Utilizing the full range of benefits of distribution automation in overhead line networks requires reliable locating and signaling of earth faults and short circuits in overhead line networks. With SICAM FSI (Fault Sensor Indicator), Siemens now offers a fault detection device for MV overhead line networks.SICAM FSI is available in 2 versions: -6MD2314-1AB10 without communication: The faults are signaled directly at the device by LEDs. Depending on the fault state, a specific flashing light is generated.-6MD2314-1AB11 - with communication: In addition to local LED display, earth faults and short circuits are transferred to a gateway (SICAM FCG) via a secured radio connection. SICAM FCG (Fault Collector Gateway) establishes the connection to a higher-level control center via GPRS and sends the messages to the control center using the standardized telecontrol protocol IEC 60870-5-104 or via XMPP

SICAM Fault Passage Indicator (FPI) is a device that is used for detection and signalling of short circuit and earth-fault on medium voltage cable networks.4 external current sensors detect the phase faults (R, Y, B) and earth-fault (E).The current sensor detects phase fault and earth-fault current based on the set current threshold detection and communicate to SICAM FPI via an optical signal.By using the rotary switch available on the individual sensor, you can set the fault current threshold for phase sensors from 200 A to 1200 A (Type 1 Series), 200 A to 800 A (Type 2 Series) and for earth sensor from 10 A to 100 A (Type 1 Series), 40 A to 300 A (Type 2 Series).When the current exceeds the set threshold level, the current sensor provides an input via plastic fibre-optic cable to SICAM FPI. In this condition, the corresponding LEDs blink. In normal operating condition, there is no LED indication.SICAM FPI is used as a fault detection and indication unit. SICAM FPI is used in the feeder and distribution automation of secondary medium-voltage systems that ranges from 10 kV to 36 kV.

The key to continuously improving power supply is essentially in depth knowledge of the relevant conditions of the local network. This is achieved through the use of all available sources connected to the system. Siemens offers a complete portfolio for network monitoring, power quality recording, fault recording, phasor measurement and system software application. Power quality and measurements supports power supply utilities and consumers with solutions required for the precise measurement, recording and reporting of the necessary distribution network data used to continuously determine, adapt and improve the power quality.SICAM FCM the finger on the pulse of your distribution Network SICAM FCM (Feeder Condition Monitor) is a short circuit and ground fault indicator with direction indication which uses protection algorithms and latest low power sensor technology according to IEC 60044, yielding top results, particularly in isolated or compensated distribution networks.SICAM FCM offers comprehensive measured values to monitor the load of distribution network components thus providing accurate data on the network condition. Live values, e.g. of a transformer operated at overload, allow countermeasures to be taken in time such as load shedding or reducing the feedback power in the affected network segment. In order to correctly evaluate the condition of the distribution network, SICAM FCM provides all relevant data via a Modbus RTU interface.

The SICAM Fault Collector Gateway (FCG) device receives both the load current values and distribution line faults via the SICAM Fault Sensor Indicator (FSI)The received information status and events are transmitted to the control center based on the IEC 60870-5-104 protocol or to the Siemens FLiC service using the XMPP protocol. The fault detected by SICAM FSI is communicated to SICAM FCG via short-range radio (SRR) communication within a distance of 100 meters.SICAM FCG provides 6 binary inputs and 3 binary outputs. SICAM FCG can be configured and diagnosed locally using the Web GUI by connecting to a PC or laptop computer or remotely via General Packet Radio Service (GPRS).The SICAM FCG has a plastic housing and it is strongly recommended to mount it within a metal cabinet for additional protection. The Global System for Mobile Communications (GSM) and short-range radio antenna are mounted outside the metallic cabinet. SICAM FSI firmware and parameters can be updated from the SICAM FCG.SICAM FCG Web GUI allows you to configure the parameters, display error and event log, upgrade of firmware, and download the configuration.
