Smart Power Distribution

Moeller Electric has launched two smart power distribution packages for motor control and power control centres.

The new packages cater to different ends of the same market, and represent refinements into standard product formats of power distribution systems previously built to a wide variety of customer specifications.

At the high-end of the market, the Expert Networking Package (or ENP) focuses on the user who needs all available power distribution data.

The second, or Basic Networking Package (BNP), focuses on bringing to the operator only essential core data such as the on/off/tripped status, actual current and voltage.

Moeller Electric's goal with both packages is to lower to more attractive pricing levels its networking solutions for power distribution and motor control centres.

It claims enhanced network functionality as the chief customer benefit when compared with other standard solutions on the market.

The Expert Networking Package is made up of networked components comprising a decentralised power control operator system for monitoring, control and diagnostics; intelligent terminals for simple and cost-effective linkage to PLC and DCS; a motor control unit for decentralised protection and control, a new range of NZM circuit breakers for FDT technology communication and parameterisation; a soft starter for motor control via Profimod-ZWK or integrated communication interface; and a field-bus wiring system.

The new NZM circuit breaker range covers a power range from 15 to 1600 amps with just four devices. Network access and the provision of data on status, history and parameters are handled by the standard Profibus-DP interface and data management module (EN50170), which is the European market leader.

There is also the IZM circuit breaker for use with currents from 600 to 6300 amps, which can be networked via Moeller's standard network Profibus-DP to allow access via Ethernet.

ENP is completed by standardised interfaces such as OPC, OLE and XML, which make the data from the distribution panel available in most SCADA systems.

Enhancements for the Expert Networking Package are scheduled for launch later this year.

The first of these will be ZES, a follow-up system for the widely used Profimod-ZWK motor control and protection system with adapted field-bus wiring.

ZES will feature innovative Rogowski sensor technology for effective current measuring, large sensor ranges from 0,2 to 1600 amps, a plugable bus module to access different field-buses, the latest Device Type Manager configuration technology, and an external parameter module to achieve device replacement with automatic configuration.

The second of the Moeller Electric's new packages, the Basic Networking Package, is a powerful maintenance tool that brings network benefits to the role and work of the maintenance electrician, so that he can define the actual status and severity of any fault, and from there decide what needs to be done.

For detailed visualisation of the power panels, the operator needs only a personal computer with intranet and web browser.

Although BNP is not a SCADA system, its data can easily be adapted to SCADA by means of an external data socket (Profibus-DP), which is an optional extra.

Moeller Electric claims that BNP reduces the quantity of data to a realistic level, and minimises networking costs.

The company anticipates accelerating demand for both the BNP and ENP packages, which are presently being introduced to customers nationwide through a series of presentations in major centres.
