At a glance  Low NOx burners which allow for a degree of customisation and in-situ adjustment were selected to help meet the new emissions limits.  System operators are a key link in monitoring and managing the installations to optimise each boiler’s performance.  Babcock has refined its project delivery with each boiler completed, reducing the timeline to less than half that of the first installation.

each unit, we are proud to have local expertise to address local challenges,” says Gerber. “As South Africa’s leading steam generation service provider, Babcock has all the engineering disciplines in-house to deliver a project of this scope successfully – from process, thermal and control instrumentation, to mechanical and piping engineering capabilities – ensuring support throughout the project life cycle. “We are proud to be involved in a project of this nature

Tracking critical parameters in power quality

Power quality measurements can be complex to set up and frustrating when critical events are missed. Comtest, Fluke’s Local Channel Partner, has introduced the new Fluke 1770 Series which captures more than 500 power quality parameters by default – so critical power quality events are never missed – from fast transients up to 8 kV, harmonics up to 30 kHz, dips and swells, as well as the voltage, current and power measurements that enable technicians to characterise electrical systems. “The Fluke 1770 Series walks technicians through the setup to eliminate any measurement errors and ensure all the correct parameters are selected,” said Frank Healy, Product Manager. “It ensures the right data is always col- lected and helps technicians identify issues faster and more clearly.” The 1770 Series features: - Automatic measurement of power and power quality parameters – critical power quality data is captured as soon as a session is started, without extensive setup or selections

- Intuitive user interface – the streamlined user in- terface makes it easy to navigate between meas- urement parameters like V/A/Hz, power, dips and swells, harmonics, unbalance, or PQ health, at the push of a button. - Capture of high-speed voltage transients – dam- aging high-speed high-magnitude transients are captured so effects can be mitigated before equip- ment fails. Voltage transients negatively impact otherwise healthy systems every day, and their potential to damage equipment should not be underestimated. Fluke 1775 and 1777 capture high-speed transients faster than previous models by leveraging the power of the latest Intel Cyclone FPGA. With a sample rate of 20 MS/s users can effectively capture, troubleshoot and mitigate the most damaging power quality issues. Fluke 1770 Series Power Quality Analysers are sup- plied standard with the powerful Fluke Energy Analyse Plus software, enabling users to analyse power quality data immediately, without extensive training required. It enables technicians to compare results to historical values, benchmark against industry norms, compare measured data to local conditions, and create a more complete picture of what is occurring across the facility – even as the data is still being collected. With Fluke Energy Analyse Plus, technicians can create customised reports or leverage built-in one-click reporting to industry standards like EN 50160, IEEE 519, and GOST 33073.
