New metering simplifies southern Africa’s power quality

The newest addition to Schneider Electric’s PowerLogic portfolio of power and energy meters introduces power quality compliance and analyses capabilities that were once reserved for more advanced meters. In accordance with power quality standards IEC 61000-4-30 Class S and IEC 62586, the PowerLogic PM8000 series meters are ideal for helping to en-

Power quality monitoring is crucial for power-critical facilities like hospitals, data centres, and large manufacturers. Schneider Elec- tric designed the PM8000 series to aid with both PQ compliance monitoring and analysis. Data accuracy is assured to IEC 61000-4-30 Class S and IEC 62586 standards when verifying contractual supply levels. If a PQ event does occur, the patented disturbance direction detection feature helps identify the location by determining if it occurred upstream or downstream of the meter, so correcting the problem is much faster. Engineered on a compact, modular and flexible platform, the PowerLogic PM8000 series meters have the versatility to perform nearly any metering job at key points throughout a facility. The highly-accurate, reliable meters are compliant with ANSI C12.20 Class 0.2, IEC 62053-22 Class 0.2S (real energy), and IEC 61557-12.

sure contractual obligations for the quality of your electrical supply. The meters also have extensive power quality analysis capabilities, such as EN 50160 compliance, sag/ swell detection, waveform capture, disturbance direction detection, and trending and forecasting, to help facility managers detect, mitigate and correct adverse con- ditions.

Gen2 Switch elevator Lost productivity due to ongoing load shed- ding in South Africa can be mitigated with the latest technological innovation fromOtis – the Gen2 Switch elevator.The Gen2 Switch is powered by battery technology to ensure continued operation during a power outage, “A major advan-

WIDE.

tage of the Gen2 Switch is that it is designed to con- tinue running even during power out- ages thanks to a built-in battery,” said Hayley Elw- en, marketing and business develop- men t manage r, Otis . “Despite the recent increase in grid volatility lead- ing into winter, the

Gen2 Switch provides property owners with the peace of mind that the lift in their build- ings will continue running during power outages.” Under normal running mode, the Gen2 Switch power supply charges a pack of batteries, which in turn supplies power to the lift motor. In the event of a power failure, the battery pack continues to operate the lift for up to 100 trips in an eight-story building.The battery system is compatible with alternative energy sources like solar panels and wind power.The battery is made of 97 % recycled materials, and is itself 90 % recyclable.
