The REJ603 relay is used for selective short-circuit and earth-fault protection of feeders in secondary distribution networks, as well as for transformer protection in utilities and industry.

The relay is a self-powered digital relay that does not require an external auxiliary supply voltage, making it ideal even for installations in remote areas where auxiliary power is not available.

The relay operates from a current transformer.

The REJ603 is mainly used in Ring Main Units (RMUs) in distribution networks.

The relay provides earth current measurement by internal calculation, or it can measure earth current from an external core balanced current transformer (CBCT).

The main features of the relay are

Self-powered three-phase non-directional overcurrent and earth fault protection with DMT and IDMT characteristics

Dual earth fault measurement modes – internal vector summing or external CBCT inputs

Integration of IDMT curves (IEC and special) in a single product to www.ge-drive.com meet the time-coordinated requirements of secondary distribution protection

Protection blocking via second harmonic measurement to ensure stability during transformer magnetic surges

Capacitive discharge pulse output for low-energy trip coils

Built-in manual reset electromechanical sign for trip indication

Easy setup via DIP switches, protected by transparent cover

Compact design and mounting for ring main unit (RMU) applications

Test equipment for testing the entire program, including primary CTs, relays and trip coils

Operating instructions

The combined overcurrent and earth fault relay is a secondary relay that is connected to the current transformer of the protected object.

In addition to the measurements (inputs), the relay receives from the current transformer the energy required for its own operation and for tripping the circuit breakers.

There are two LEDs on the front panel. The green “Ready” indicator lights up when the minimum current required for operation is available, indicating that the relay is operating.

When a fault is detected, the relay will trip the circuit breaker according to the setting.

The relay will also perform periodic internal health checks and notify the user of any faults within the relay.

Internal relay faults are indicated by the red LED “IRF” indicator.

The overcurrent device will operate when the phase current exceeds the set run time for timed operation or the calculated run time for inverse time limit operation.

Operation. Similarly, the high level I>> of the overcurrent device will actuate when the set operation time has expired.

The ground fault unit operates when the ground fault current exceeds the set operation time for timed operation or the calculated operation time for inverse time limit operation.

Similarly, the high level I0>> of the ground-fault unit operates when the set operation time expires.

The low-level rectification stage of the overcurrent unit and the low-level rectification stage of the ground-fault unit can have a deterministic time or inverse deterministic minimum time (IDMT) characteristic.

When the IDMT characteristic is selected, four standard time/current curves and three special time/current curves are available.

The standard curves conform to BS142 and IEC 60255 and are referred to as normal inverse time, extreme inverse time, extreme inverse time and long time inverse time.

In addition, three special curves are available, namely the RI curve, the HR fuse curve and the FR fuse curve.

Security in Distribution Automation

General Security in Distribution Automation

Technological advances and breakthroughs have led to a significant evolution of the power grid. www.ge-drive.com As a result, the emerging “Smart Grid” and “Internet of Things” are rapidly becoming a reality. At the heart of these intelligent advances are specialized IT systems – a variety of control and automation solutions, such as distribution automation systems.

solutions, such as distribution automation systems. Automation systems are becoming increasingly interconnected in order to provide comprehensive real-time information to end-users and to achieve higher reliability and greater control. To address the increased risks associated with these interconnections, ABB offers a wide range of cybersecurity products and solutions for automation systems and critical infrastructure.

The new generation of automation systems utilizes open standards such as IEC 61850 and commercially available technologies, in particular communication protocols based on Ethernet and TCP/IP. They can also be connected to external networks, such as office intranet systems and the Internet. These changes in technology, including the adoption of open IT standards, have brought significant benefits from an operational standpoint, but they have also created cybersecurity issues previously known only to office or corporate IT systems.

To address cybersecurity risks, open IT standards are equipped with cybersecurity mechanisms. These mechanisms have been developed in a large number of enterprise applications and are proven technologies. They enable the design, development and continuous improvement of cybersecurity solutions for control systems, including distribution automation applications.

ABB recognizes the importance of cybersecurity and its role in improving the safety of power distribution networks. Customers investing in new ABB technologies can rely on system solutions that prioritize reliability and safety.

At ABB, we are meeting cybersecurity requirements at the system level and at the product level to support cybersecurity standards or recommendations from organizations such as NERC CIP, IEC 62351. IEC 62443. IEEE 1686. ENISA, and BDEW white papers.

System Hardening Ground Rules

Today’s distribution automation systems are essentially specialized IT systems.

Therefore, several of the rules for hardening automation systems apply to these systems as well. From an automation system perspective, protection and control relays are at the bottom of the hierarchy, closest to the actual main processes. It is important to apply the “defense-in-depth” information security concept, whereby each layer in the system is capable of protecting the automation system, and therefore the protection and control relays are part of this concept. The following points should be considered when planning system protection.

– Recognize and familiarize yourself with all parts of the system and the system’s communication links

– Remove all unnecessary communication links from the system

– Rate the safety level of the remaining connections and improve them using applicable methods

– Harden the system by removing or deactivating all unused processes, communication ports, and services

– Check that all applicable parts of the entire system are backed up

– Collect and store backups of system components and keep them up to date

– Remove all unnecessary user accounts

– Define password policies

– Change default passwords and use strong passwords

– Check that strong encryption and authentication is used for links from the substation to higher-level systems

– Separate public (untrusted) from automated (trusted) networks

– Isolate traffic and networks

– Use firewalls and demilitarized zones

– Evaluate systems regularly

– Use malware protection in workstations and keep it up to date It is important to utilize defense-in-depth concepts when designing automated system security. Connecting devices directly to the Internet is not recommended without adequate additional security components. Security controls should be used for the different layers and interfaces in the system. In addition to product features, strong security means enabling and using available features and enforcing their use according to company policy. Proper training of personnel accessing and using the system is also required.
