The 6MD66 high-voltage bay control unit is the control unit for high voltage bays from the SIPROTEC 4 relay series. Because of its integrated functions, it is an optimum, low-cost solution for high-voltage switch bays. The 6MD66 high-voltage bay controller unit also has the same design (look and feel) as the other protection and combined units of the SIPROTEC 4 relay series. Configuration is performed in a standardised way with the easy-to-use DIGSI 4 configuration tool.
For operation, a large graphic display with a keyboard is available. The important operating actions are performed in a simple and intuitive way, e.g. alarm list display or switch gear control. The operator panel can be mounted separately from the unit, if required. Thus, flexibility with regard to the mounting position of the unit is ensured. Integrated key-operated switches control the switching authority and authorisation for switching without interlocking. High-accuracy measurement (± 0.5 %) for voltage, current and calculated values P and Q are another feature of the unit.

Transformer differential protection
SIPROTEC 7UT613
The SIPROTEC 7UT613 differential protection relays are used for fast and selective fault clearing of short-circuits in transformers of all voltage levels and also in rotating electric machines like motors and generators, for short lines and busbars.
Features
The specific application can be chosen by parameterization. In this way an optimal adaptation of the relay to the protected object can be achieved.
In addition to the differential function, a backup overcurrent protection for 1 winding/ star point is integrated in the relay. Optionally, a low or high-impedance restricted earth-fault protection, a negative-sequence protection and a breaker failure protection can be used. 7UT613 features 4 voltage inputs. With this option an overvoltage and undervoltage protection is available as well as frequency protection, reverse / forward power protection, fuse failure monitor and overexcitation protection. With external temperature monitoring boxes (thermo-boxes) temperatures can be measured and monitored in the relay. Therefore, complete thermal monitoring of a transformer is possible, e.g. hot-spot calculation of the oil temperature.
7UT613 features full coverage of applications without external relays by the option of multiple protection functions e.g. overcurrent protection is available for each winding or measurement location of a transformer. Other functions are available twice: ground-fault differential protection, breaker failure protection and overload protection. Furthermore, up to 12 user-defined (flxible) protection functions may be activated by the customer with the choice of measured voltages, currents, power and frequency as input variables. The relays provide easy-to-use local control and automation functions.
The integrated programmable logic (CFC) allows the users to implement their own functions, e.g. for the automation of switchgear (interlocking). User-defined messages can be generated as well. The flexible communication interfaces are open for modem communication architectures with control system.

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 with high 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 (V>, V<, f>, f
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 7SD610 relay is a differential protection relay suitable for all types of applications and incorporating all those functions required for differential protection of lines, cables, and transformers. Transformers and compensation coils within the differential protection zone are protected by means of integrated functions, which were previously to be found only in transformer differential protection. It is also well-suited for complex applications such as series and parallel compensation of lines and cables.
It is designed to provide differential and directional backup protection for all voltage levels and types of networks. The relay features high speed and phase-selective short circuit measurement. The unit is thus suitable for single-phase and three-phase fault clearance.
Digital data communication for differential current measurement is effected via fiber-optic cables, networks or pilot wires connections so that the line ends can be quite far apart. The serial protection interface (R2R interface) of the relay can flexibly be adapted to the requirements of all existing communication media. If the communication method is changed, flexible retrofitting of communication modules to the existing configuration is possible.
Apart from the main protection function, i.e. the differential protection, the 7SD610 has a full range of configurable emergency and/or backup protection functions such as phase and earth over current protection with directional elements if voltage transformers are connected. Overload, under and over-voltage/frequency and breaker failure protection round off the functional scope of the 7SD610.

The SIPROTEC Compact 7RW80 is a numerical, multi function relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If the SIPROTEC Compact 7RW80 detects any deviation from the permitted voltage, frequency or over excitation values, it will respond according to the values set. The relay can also be applied for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops.
An integrated load restoration function allows the re-establishment of the power system after recovery of the system frequency. The 7RW80 features “flexible protection functionsâ€Â. 20 additional protection functions can be created by the user. For example, a rate-of-frequency change or a rate of- voltage change function can be created. The relay provides circuit-breaker control, additional primary switching devices (grounding switches, transfer switches and isolating switches) can also be controlled from the relay.
Automation or PLC logic functionality is also implemented in the relay. The integrated programmable logic (CFC) allows the user to add own functions, e.g. for the automation of switchgear (including: interlocking, transfer and load shedding schemes). The user is also allowed to generate user-defined messages.
The communication module is independent from the protection. It can easily be exchanged or upgraded to future communication protocols.

Pluggable current and voltage terminals
Binary input thresholds settable using DIGSI (3 stages)
9 programmable function keys
6-line display
Buffer battery exchangeable from the front

The line differential protection SIPROTEC 7SD80 has been conceived for selective line protection of power cables and overhead lines up to 24km for all kind of starpoint configurations. The implemented phase comparison algorithm is a fast and stable method for line protection in industry and distribution grids. The protection interface communication is carried out directly without external equipment over copper wires, optical fibers or both in redundancy. The wide scope of non directional and directional functions can be applied miscellaneously as emergency functions as well as backup functions. For instance the 7SD80 enables simplified and cost saving concepts for meshed grids and busbar protection by means of reverse interlocking. Fast and selective tripping is guaranteed even if the communication fails between the relays. The scope of functions includes protection functions as well as functions for control and monitoring. The interoperable connectivity to substation control systems is give by standard protocols like IEC61850. The general concept of redundancy for protection and its communication gets completed by Ethernet redundancy protocols (PRP, HSR, RSTP) and thus increases the total system availability. Integrated functions for commissioning help and easy settings lead to short commissioning times.
