1 Relion 620 series Transformer protection and control RET620 Flexibility for utility and industrial power distribution systems

2 Compact protection and control with voltage regulation for two-winding power transformers RET620 is a dedicated transformer management relay for protection, control, measurement and supervision of both power and step-up transformers, including power generator-transformer blocks, in utility and industrial power distribution systems. RET620 is also ideal for voltage regulation. Application RET620 has been designed to be the main protection for two-winding power transformers and power generatortransformer blocks. The transformer management relay can be used in various single or double-busbar applications, with either one or two breakers and numerous switching devices. It also supports a substantial number of both manually and motor-operated disconnectors and earthing switches. RET620 features three-phase transformer differential protection, one multi-slope stabilized (biased) stage and one instantaneous stage, providing a fast and selective protection for phase-to-phase short circuits, winding interturn-faults and bushing flash-overs. There is also a choice between either low or high-impedance restricted earth-fault (REF) protection. In addition to transformer protection and control, RET620 offers voltage regulator control. The voltage regulator has been designed for power transformers with a motor-driven on-load tap-changer and offers both manual and automatic tap-changer control. To minimize the effects of an arc fault, RET620 can be equipped with high-speed outputs decreasing the operate time by four to six milliseconds compared to conventional outputs. The wide functionality offering, combined with the ability to run large configurations, makes RET620 ideal for more advanced transformer protection and control. RET620 also offers extensive possibilities to easily tailor the configurations to application-specific requirements using the IEC 6850-complient Protection and Control IED Manager PCM600. Human-machine interface As a member of the Relion product family, RET620 shares the same human-machine interface (HMI) look and feel as the other Relion protection and control relays and IEDs. The same look and feel includes the location of a push button with a certain function and the menu structure. RET620 is equipped with a large graphical display which can show customizable single-line diagrams (SLD) with position indication for switching devices. Also measured values provided by the configuration can be displayed. The SLDs can be customized using PCM600 and can have multiple pages for easy access to selected information. The SLDs can be accessed not only locally but also via the web browser-based HMI. The 620 series HMI is distinguished by sixteen configurable two-state push buttons that can be used as additional alarm LEDs or control buttons for various tasks such as blocking, adjusting setting groups or triggering the disturbance recorder. Standardized communication and redundancy RET620 fully supports the IEC 6850 standard for communication and interoperability of substation automation devices, including fast GOOSE messaging and now also IEC LE process bus and Edition 2, offering substantial benefits in terms of extended interoperability. The transformer management relay further supports both the parallel redundancy protocol (PRP) and the high-availability seamless redundancy (HSR) protocol, together with the DNP3, IEC and Modbus protocols. With the protocol adapter SPA-ZC 302, Profibus DVP can also be used. RET620 is able to use two communication protocols simultaneously. For redundant Ethernet communication, RET620 offers either two optical or two galvanic Ethernet network interfaces. A third port with a galvanic Ethernet network interface provides connectivity of any other Ethernet device to an IEC 6850 station bus inside a switchgear bay. The redundant Ethernet solution can be built on the Ethernet-based IEC 6850, Modbus and DNP3 protocols. The implementation of the IEC 6850 standard in RET620 covers both vertical and horizontal communication, including GOOSE messaging with both binary and analog signals as well as parameter setting according to IEC In addition, process bus with sending sampled values of both analog voltages and currents and receiving sampled values of voltages is introduced. The sampled values can be used, for instance, for synchro-check to ensure safe interconnection of two networks, and both in conventional instrument transformer as well as sensor-based applications. For process bus applications, which require high-accuracy 2 Transformer protection and control RET620

3 time synchronization, IEEE 588 V2 is used, with a time stamp resolution of not more than four microseconds. IEEE 588 V2 is supported in all variants with a redundant Ethernet communication module. In addition, RET620 supports synchronization over Ethernet using SNTP or over a separate bus using IRIG-B.
