Diversified industrial manufacturer Eaton has launched a comprehensive range of power protection relays that are ideally suited for use in the company’s Medium Voltage (MV) switchgear. Thanks to the microprocessor-based design the devices make it possible to eliminate unnecessary trippings, isolate faults, and protect motors and cables, thus offering sophisticated protection for many power applications. The relays also provide detailed information that enables users to better manage their systems, subsequently contributing to a safe and reliable energy supply for applications in utility distribution networks and industrial environments or other power systems.

Eaton’s family of relays consists of devices for a broad range of protection and control tasks including directional and non-directional feeder protection, overcurrent and earth fault protection (OC&EF), voltage and frequency protection, motor and generator protection, generator and transformer differential protection, and power differential protection. These functions partly also include voltage measurement.

All relays have been designed according to the IEC 61850 standard and are internationally certified (KEMA, UL, Gost-R, CSA). An integrated user-friendly status display offers clear data visualisation and intuitive operation while plausibility checks prevent the user from accidently entering unacceptable inputs. The display allows for immediate evaluation of individual measurements on site. At the same time, direct connection with the SCADA system is easily possible via its control interface. As the relays feature analysis and graphical representation of the fault details, fault recording becomes extremely transparent. The integrated non-volatile disturbance recorder registers up to 120 s with 32 samples per cycle. Import and export of fault records can be done in the ASCII and Comtrade formats.

All current and ground current inputs are designed for 1 and 5 A. The relay terminals can easily be integrated into, and removed from, the switchgear enclosure. To ensure safe operation the current connections are equipped with automatic short circuit connectors. A wide range power supply unit covers all standard auxiliary voltages, both for AC and DC. Eaton also offers appropriate software that allows the user to adjust the nominal voltage of the voltage inputs and the switching thresholds of the digital inputs. Besides parameter setting and validity checks, the software supports offline configuration of all relay types, reading and evaluating statistical data and measuring values, commissioning functions as well as error analysis.

The Eaton relays have specifically been customised for the following Eaton MV switchgear systems: Xiria, Xiria E (extendable version), SVS, Power Xpert® FMX and UX.

Finder’s 77 Series “single pole” solid state relays are now available in eight new versions, with a 30A current rating to complement the existing 5A models.

With distinct models for zero-voltage and instantaneous switch-on, the former is particularly suited for lighting control where zero-voltage switching can significantly reduce high inrush currents. Instantaneous switch-on provides near instant switching for high speed operation and simultaneous switching in multi-phase circuits, such as three phase motors.

The very high inrush current capability of 520A (10ms) ensures reliability over a long life in a wide range of applications, particularly the switching of lighting where power factor compensation and electronic ballasts have historically been problematic – but it is also ideal for the control of heating, solenoids and motors.

In 22.5mm housing incorporating the heat sink and designed for 35mm rail mounting, the relays are ideal for use in control panels and cabinets in industrial and commercial applications.

Capable of switching single phase motors up to 2.5kW or lamp loads up to 6000W, and with the benefit of silent, high speed switching, they lend themselves to use in a host of environments. Input voltages of 230Vac and 24Vdc.

With increasing health and safety demands and the need to protect valuable equipment, Finder’s new 70 Series modular rail-mounted monitoring relays provide a solution by offering maximum flexibility in monitoring a range of electrical supply parameters, in compact, easy to adjust units. For example, machine safety legislation (IEC/EN/BS60204-1) requires that portable or semi-portable motor-driven equipment be prevented from starting up in the wrong direction should the local phases be reversed, and a phase reversal monitoring relay can provide for that.

Finder’s new relays are ideal for monitoring supplies to machinery, equipment, and installations where failure or variation outside acceptable limits may result in damage to equipment, danger to personnel, or disruption to critical processes or procedures. Featuring ‘positive safety logic,’ the 70 Series will ensure that any failure mode results in the output relay assuming its de-energized position. With a selectable fault memory (lock-out), safety is increased by preventing uncontrolled restarting of equipment.

With a wide range of adjustments to maximize application flexibility, the monitoring relays feature two or three colour LED indicators for immediate visual indication of supply status. The functions and values are programmable from the front face, simplifying set-up and adjustment.

Within the 70 Series range are units designed to monitor single and 3-phase supplies for under-voltage, over-voltage, voltage within set limits, and for neutral loss, phase loss, phase rotation and asymmetry. The four monitoring relays in the 70 Series range (three of which are multifunctional) offer a selection of voltage limits between 170 – 270 for single phase, and 300– 480 for three-phase supplies, a switch off delay time between 0.5 – 60 seconds, and 4 – 25% variation of phase asymmetry. The modules are available in 17.mm or 35mm, dependent on type.

The revolutionary SmartWire-DT system from Eaton’s Electrical Sector, which virtually eliminates the need for conventional control wiring in panels and on machines, is now even more versatile and convenient. This follows the addition of devices with integral SmartWire-DT connectivity to two key product ranges – easy800 control relays and PKE motor-protection circuit breakers.

In many applications, easy800 programmable control relays with SmartWire-DT make it possible to implement sophisticated control systems without the need to use programmable controllers (PLCs), which means big savings in costs and complexity. In addition, Eaton’s easySoft-Pro software makes easy800 relays simple to program, even for users who have no specialist programming knowledge or experience.

The new easy800 relays are suitable for applications with up to 320 I/O and are programmed using straightforward and well-known ladder diagram techniques. The easySoft-Pro programming software now includes SmartWire Assist to configure external devices, allowing control systems that incorporate the new relays to be drawn, configured, programmed and tested using just this one intuitive software package.

Equally well suited for use in control systems based on easy800 relays, and those based on conventional PLCs, PKE motor-protection circuit breakers with SmartWire-DT allow users to monitor the operation of their motors in detail and in real time. The PKE units can report via the SmartWire-DT connection a wide range of operating parameters that include motor current, motor fault conditions and overload status. This is achieved without the need for additional hardware like current transformers and specialist relays, which are not only costly to buy, but are also inconvenient to fit and wire.

A key benefit of the information supplied by PKE units with SmartWire-DT connectivity is that, in many cases, it allows developing problems to be identified and addressed before a motor trip occurs, thereby greatly reducing downtime and costly production losses.

SmartWire-DT from Eaton is a powerful and versatile communications system that enables switching and control devices, such as contactors, circuit breakers and pushbuttons, as well as analogue I/O devices, to be connected quickly and simply using pre-fabricated plug-in cables. This saves time in building and testing control systems, as well as virtually eliminating the risk of wiring errors while greatly increasing the ease with which future modifications can be made.
