Voltage instability\u003C/strong\u003E\u003Cbr /\u003E\nThis is in part a side effect of the high or low voltage electricity supply from the network. High voltage does not increase equipment power and is detrimental to equipment performance and longevity, and low voltage can cause reduced productivity. Voltage optimisation ensures the voltage supplied to the system is stable, as required by the equipment on site.\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003E\u003Cstrong\u003E2. Harmonic voltages and currents\u003C/strong\u003E\u003Cbr /\u003E\nThese are introduced by a range of common electrical devices which distorts the AC wave form and increases power usage. By introducing harmonic filters or reactors, the result is more efficient power usage and cost savings.\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003E\u003Cstrong\u003E3. Poor power factor\u003C/strong\u003E\u003Cbr /\u003E\nThis refers to an excess of reactive power in the system. This reactive power does not perform any real work. As such, it is wasteful and costly. Power Factor Correction (PFC) reduces and can almost eliminate this reactive power, reduce energy costs and stop equipment overheating, nuisance tripping and motor failure.\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003E\u003Cstrong\u003ELearn more\u003C/strong\u003E\u003Cbr /\u003E\nClick \u003Ca href=\u0022https://www.youtube.com/watch?v=q4VjsHq4LOk\u0022\u003E\u003Cstrong\u003Ehere\u003C/strong\u003E\u003C/a\u003E to watch this informative video from Schneider, on the various power quality issues!\u003C/p\u003E\n\u003Cp class=\u0022text-align-justify\u0022\u003E\u003Cstrong\u003Ea-eberle\u0027s PQ-Box 150\u003C/strong\u003E\u003Cbr /\u003E\nPower quality takes a huge leap forward with\u00A0a-eberle\u2019s\u00A0PQ-Box 150 power grid analyser.

In collaboration with Philips Lighting and Growthpoint Properties, our team designed and installed a circadian rhythm lighting system in all ground floor meeting rooms at Growthpoint\u2019s Johannesburg head office. The mandate for this project encompassed selection of an energy efficient lighting system, with modern aesthetics, to enhance work productivity and the well-being of the building\u2019s occupants.\u003C/p\u003E\n\u003Cp\u003EThis environmentally-friendly project \u2013 our first local installation of circadian rhythm lighting - showcases Growthpoint\u2019s commitment to innovative and green buildings.

This advanced technology has numerous health benefits and occupants of the building will feel more alert, be more productive and benefit from working in a more natural lighting environment. Fine-tuned soft white lighting helps occupants relax, while bright white light assists occupants to remain focused and feel energised.\u003C/p\u003E\n\u003Cp\u003ELighting for circadian systems requires different metrics from those used for conventional architectural lighting. In specifying lighting for this circadian system, the team needed to evaluate the required light levels of the meeting rooms and spectral composition, as well as timing and duration of lighting exposure.

The biorhythm support curve is designed to strengthen the circadian system and improve the sleep-wake cycle, resulting in improved health, increased daytime wakefulness and a better state of mind. The natural daylight curve follows the dynamics of daylight and provides a connection with the outdoor, while boosting energy levels and performance of those inside the office during the day.\u003C/p\u003E\n\u003Cp\u003EFor example, at the start of a work day, illuminance levels are increased to 500 lux to increase alertness and improve performance. Bright light keeps people energised throughout the day, stabilising the sleep-wake cycle and preventing unnatural delays in sleep onset in the evening. Illuminance levels are increased slightly later in the day to enhance visual performance, stimulate mood and strengthen the body clock. Light levels and colour temperatures are reduced later in the day to prepare people to switch from the work to home environment.\u003C/p\u003E\n\u003Cp\u003EWerner van Antwerpen of Growthpoint Properties had this to say about the new lighting installation: \u003Cem\u003E\u201CInnovation, green buildings and increasing staff productivity within our tenant space, have always been a main focus within Growthpoint.
