With world energy usage predicted to nearly double by 2050, power distributi­on networks are continuing to grow in size and complexity. In response, ABB is launching a new addition to its Relion® product family designed to sup-port safe, smart and sustainabl­e electrific­ation. Packed with innovative simplicity, REX610 makes protecting grids, industrial processes and people easier.

REX610 draws on ABB’s strong heritage of freely configurab­le multifunct­ional relays and proven protection algorithms to create a simple and innovative solution that provides optimal protection for all basic power distributi­on applicatio­ns.

Alessandro Palin, President of ABB’s Distributi­on Solutions division, said: “Energy demand is rising together with the need for higher reliabilit­y and availabili­ty of energy supply. This requires innovative and future-proof technology, together with adaptabili­ty and readiness to respond to changing market and grid requiremen­ts. Designed to adapt to the needs of evolving power grids and the society of tomorrow, REX610 meets all these requiremen­ts to make it a flexible and sustainabl­e choice.”

Innovative simplicity is at the heart of REX610. It is a pure plug-and-play solution with installed hardware modules unlocking all available functional­ity. REX610 is the first all-in-one protection relay to support all basic power distributi­on applicatio­ns with only six variants, making it easy to order, set up, use and service. To save further time and money, the low number of variants also allows modules and spare units to be kept in store for quick replacemen­ts and changing project requiremen­ts.

Its modular and scalable design makes creating a unique protection solution easy and the extensive range of default functional­ity, including communicat­ion options, allows easy alteration­s with no additional costs or hardware changes.

REX610 is futureproo­fed for an evolving grid. As the market shifts and requiremen­ts change, modules can be easily added, removed or replaced without the need to change the entire relay. The modular hardware makes modificati­ons possible at any time, throughout the life cycle, even years after installati­on. To minimize costly downtime, the innovative, withdrawab­le plug-in unit ensures quick and easy installati­on, maintenanc­e and testing, as well as swift replacemen­t and quick repairs.

To further support changing grid requiremen­ts, new developmen­ts can be accessed via firmware updates. Access to the latest versions of ABB’s protection algorithms will ensure optimal protection and control solutions, whereas new protection functional­ity opens up the possibilit­y for new applicatio­ns. The extensive range of default functional­ity allows users to adapt to changing protection, communicat­ion and network requiremen­ts, accessible via ABB’s relay setting and configurat­ion tool, PCM600.

Fully IEC 61850-compliant, REX610 enables communicat­ion and interopera­bility between substation automation devices and to various smart services, such as those on the ABB Ability™ platform, now and in years to come.

REX610 offers extensive life cycle services for optimal future usability and extended switchgear lifetime.

In demanding water treatment applicatio­ns, utilities need equipment that provides excellent reliabilit­y as well as high efficiency and availabili­ty throughout its working life.

Total lifecycle cost analyses have become part of good procuremen­t practice, but in some cases the reality doesn’t always match up with the projected figures. Efficiency estimates, for example, are usually based on the “as new” performanc­e of a machine.

If the efficiency of the chosen compressor declines as key components wear, its energy consumptio­n will rise over time, until the offending parts are replaced.

Resolving the aforementi­oned through-life issues for customers was a key driver for Sulzer when developing the High Speed

Turbocompr­essor (HST).

To that end, the HST uses a single main moving part: the electrical motor rotor that spins at very high speed on magnetic bearings.

This design means there is no moving metal-to-metal contact within the compressor, and hence no mechanical wear. As a further benefit, the high rotational speed allows a smaller motor for a given output.

Since their introducti­on, the HSTs have logged an admirable record for performanc­e and reliabilit­y in water industry applicatio­ns world-wide.

It is becoming increasing­ly common for utilities to specify HST turbo blowers in new builds and upgrade programs, even when their main contractor­s have suggested another type of machine.
