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.

Eaton Corporation is offering a new plug-in unit for the NZM3 circuit-breaker. The NZM3 plug-in unit allows customers to exchange the circuit-breaker in a panel simply and quickly, and it also offers benefits during service work because the system section concerned can be disconnected simply and safely.

The housing design of the base has been adapted to that of the NZM3, so that all connection options provided by the main device can also be implemented in the base. For Eaton, safety has the highest priority, and the live parts in the base are therefore automatically protected from direct contact when the circuit-breaker compartment is pulled out. The circuit-breaker also disconnects automatically as soon as the mounting screws are loosened when the circuit-breaker is in the On position or when the circuit-breaker is pushed in. In the latter case, the circuit-breaker can then only be switched on if the mounting screws between the circuit-breaker and the plug-in unit base have been tightened.

Even with the wide range of features and capabilities provided by its products, simple operation and flexibility are top priorities for Eaton: Just fit the modified NZM3 with its rear terminal bolts into the guide, tighten the bolts, and the system is already operational. An auxiliary conductor plug-in device is also available as an option. This enables the connected shunt or undervoltage releases, auxiliary contactors and also the remote operator to be tested without having to fit the circuit-breaker into the panel.  In this way, correct operation can be tested prior to commissioning. Users also do not have to change the wiring when exchanging a circuit-breaker: The auxiliary conductor plug can simply be removed from its base, fitted onto the new terminal cables and operation is restored.

Technical specifications have been set to meet the wide range of requirements in the industrial sector and are impressive in every respect: The new plug-in unit on the NZM3 from 250 - 500A can be used without any derating up to an ambient temperature of 40°C, and this includes the extensive range of accessories. For more demanding applications, the full switching capacity of the NZM3 - up to 150kA at 415VAC - can be used. The circuit-breaker can also be fitted in many positions, either vertically or turned anticlockwise/clockwise by 90°.

Diversified industrial manufacturer Eaton Corporation will be presenting the new PowerXL variable frequency drives for a rating range of up to 250 kW at this year's SPS/IPC/Drives fair in Nuremberg. The company is thus logically expanding its strategy of applying the Lean methodology to the engineering in machine and panel building. Pluggable modules enable the PowerXL variable frequency drives to be incorporated quickly and simply into Eaton's SmartWire-DT connection and communication technology which completely eliminates the need for conventional control circuit wiring. The new PowerXL variable frequency drives thus give users from the machine building sector as well as from the materials handling and building services sectors an easy-to-install, operator-friendly and energy efficient solution for driving devices such as pumps, fans, conveyor belts, cranes, winding machines, compressors or lifts.

The new PowerXL variable frequency drive series currently consists of two models: The DC1 Compact and the DA1 Advanced Machinery Drive. The DC1 is the basic model covering ratings from 0.37 to 11 kW, and was developed for applications where robust design, availability and universal functionality are the main requirements. The DA1 series is designed for ratings from 0.75 kW to 250 kW, and is suitable for the most demanding solutions requiring high performance. The PowerXL variable frequency drives also offer different open and closed-loop control methods. The DC1 controls the motor with U/f characteristics and also enables an increased torque. The PowerXL frequency inverters are thus able to operate the motors at 150% of the rated power for 60 s and at 175% for 2 s. The DA1 models also offer the user the possibility of sensorless vector control (SLV) as well closed-loop control with a rotary encoder (CLV). In sensorless vector mode the DA1 can even move from rest with a 200% torque and without the use of an encoder. The DA1 series is provided with PLC functionality and offers, in addition to a standard integrated PID controller, the possibility of powerful solutions for different applications such as cranes, lifts, winding machines and compressors.

User-friendliness was a prime objective in the development. Self-explanatory type codes, autotune functionality and convenient parameterization (with only 14 standard parameters) simplify configuration and commissioning. As well as programming via the keys on the device or alternatively via a PC, the user can copy the parameter settings from one device to another quickly and simply using a Bluetooth PC stick with an RJ45 interface.

The PowerXL variable frequency drives come as standard with the Modbus RTU and CANopen fieldbus system. The user can connect other fieldbus systems such as Profibus, Profinet, DeviceNet, EthernetIP, EtherCat, Modbus TCP and BACnet easily via fieldbus modules. As an alternative to the fieldbus connection, the PowerXL variable frequency drives can also be incorporated in the SmartWire-DT communication system. This makes it possible to not only parameterize the PowerXL frequency inverters centrally via the SmartWire-DT interface, but also to send them control commands and read diagnostic data from them. The device can also be controlled via a PROFIdrive profile which makes the full function spectrum of the PowerXL frequency inverters available.

With the focus on energy efficiency, the DA1 series supports both the standard three-phase motors that normally comply with the current IE2 and IE3 standard, as well as the highly efficient permanent magnet motors that are designed for the future IE4 standard. The devices also feature an energy optimizer that can automatically reduce the motor voltage with light loads.

The PowerXL frequency inverters supply full power up to ambient temperatures of 50°C (IP20). Eaton also offers the DA1 models up to 160 kW with protection to IP55. All devices come with international approvals (CE, cUL, UL, C-Tick, Gost-R, RoHS, DNV) and with single-phase and three-phase voltage inputs of 115 V, 230 V and 400/480 V are ideally suited for global use.

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.
