Water/Wastewater: Drive Out Distortion With a Low-Harmonic Drive
There’s a contaminant that has long troubled water and wastewater operations, and you won’t find it in the water.
Harmonic distortion is like a pollutant on a power line. It can cause electrical equipment to act erratically or shut off, resulting in unplanned downtime. And it can frustrate workers by making water treatment systems more difficult to optimize.
The IEEE 519 standard gives industry a target to achieve: a total harmonic distortion of 5% or less. The question is, how do you hit this target with minimal risk or impact to your operations?

ABB motors and drives boost efficiency of Swedish waste-to-energy plant
How can society meet its increasing demand for energy while reducing carbon emissions? Swedish utility Mälarenergi has achieved something significant as it faces this challenge head-on with its waste-to-energy plant Unit 6, one of the biggest in the world.
Mälarenergi’s waste preparation facility, boiler and smoke stack sit alongside Lake Mälaren’s pristine waters. The lake spreads out, still as glass, to the far horizon. On its shore lies Västerås, Sweden’s fifth largest city and home to 150,000 people.
Motor Control
Commander variable speed drives have established a standard of excellence in motor control since 1983 when Control Techniques launched the first world commercial vector drive. Since then, Commander has undergone several successful reiterations, each time bringing new technology and innovations to the world of automation.
The new Commander C series has been designed to be a simple and compact AC motor speed controller that meets advanced requirements in a wide range of applications and provides optimum user experience.

Pilz: Gate Safeguard
The best gate safeguard or access control is worthless if unauthorised access to your machine is possible via the IT system. A holistic safety concept is required here, that takes both machinery safety and industrial security into account. Should any security gaps emerge, loss of quality and unplanned downtimes are two of the possible scenarios. So it's all the more important to protect plant and machinery in such a way that only authorised personnel have access and manipulation of the control systems by attacks from outside is prevented.
Pilz can offer you a coherent machine access concept, which takes into account not only the safety of your machine, but also its industrial security.
