Keeping up with UPS

Published

on

A UPS is a very important piece of equipment to any business in South Africa, but purchasing one and just installing it is not enough. It needs to be maintained and monitored to make sure it operates properly when needed, writes ELRICA QUICK.

A UPS has become one of the most critical pieces of office equipment in South Africa, given the on-going power problems as well as the essential nature of technology equipment such as servers, switches and other IT equipment. However, a UPS is not simply something that can be purchased, installed and forgotten about. As essential as it is to operations, it is vital to ensure that the device itself is maintained. This is necessary to make certain that, when it is needed, the UPS will be able to perform with maximum efficiency. Simple preventative maintenance and proactive monitoring, can help businesses to ensure their UPS is always available and in good working order, ready to perform its critical tasks whenever needed.

In the past, performing preventative maintenance on UPS’ was challenging, and problems could only be resolved once they surfaced. However, today’s new UPS models offer integrated advanced monitoring, such as regular automatic status updates, through self-monitoring software. This can greatly assist in ensuring problems can be corrected before they affect the business. However, aside from this proactive monitoring, it is also important to still inspect a UPS regularly to ensure it is operating at maximum efficiency. Through regular maintenance, unnecessary downtime can be avoided, which saves businesses both time and money.

While UPS systems are designed to be reliable and durable, as they age there is an increased chance that they may malfunction either mechanically or electronically. The most common causes of UPS failure are the batteries, fans, electrolytic capacitors, Metal Oxide Varistors (MOVs) – a resistor designed to protect circuits against high transient (short term) voltage – and the relays.

Batteries do not last forever, and will typically need to be replaced at some point during the lifecycle of a UPS. The forecasted lifespan of a UPS battery is between three and five years. However, this depends on the cycles run on the battery. For example, the number of times that the UPS was dependent on the battery will impact the lifecycle of the battery. Newer UPS units include more advanced features and will send out SMS or email alerts regarding the status of the battery and UPS.  Other factors that impact the lifespan of the battery include placement and storage of the battery, ambient temperature and battery chemistry. Being proactive and being aware of these factors can help organisations ensure they obtain maximum life from their UPS batteries, and can predict and prepare for imminent failures.

Temperature has a significant impact on the life expectancy not only of batteries, but of all UPS components. Most UPSs are thus equipped with fans, to help cool the unit and keep ambient temperatures within recommended ranges. The fan will typically switch on or speed up when utility power is not available or when the temperature within the UPS surpasses a predetermined level. To prolong the life of UPS fans it is advisable to limit the scenarios in which the fan is forced to operate. Keeping the ambient temperature within the specified range, monitoring the UPS for unusual or frequent cycling, and correctly sizing the UPS for the relevant load can all help to extend the life of this component.

Electrolytic capacitors smooth out voltage fluctuations and monitoring the temperature of the environment and ensuring it remains within specified ranges, will greatly enhance the life expectancy of electrolytic capacitors.

When it comes to MOVs, they typically malfunction after being exposed to frequent and/or extreme voltage spikes. A UPS is designed to provide surge protection to connected equipment, and the MOV functions to achieve this by absorbing excess voltage. If a severe voltage spike occurs, the MOV may be destroyed. There is little that can be done to prevent the effects of extreme voltage spikes, however, it is important to ensure that if they do happen, the MOV is replaced so that the UPS can continue to provide optimal functionality.

Relays switch the battery on and off, and under normal circumstances it is unlikely that the UPS will cycle enough times to cause the relay to fail. Unusually high cycling could indicate incorrect UPS operation, and the relays and the battery may be affected. Proactive monitoring and reporting will help organisations to become alert to this type of issue, which enables proactive adjustments to be made to the firmware to prevent substantial damage or failure before it occurs.

While the majority of serviceable UPS components are designed to be touch safe, it is wise to bear in mind that a UPS is still a live piece of electrical equipment, and due care and safety procedures should always be taken. General best practices for the maintenance of UPS solutions are to be proactive, be prepared and be organised.  Proactivity is always the best approach with regard to both battery and UPS replacement. Finally, correct organisation is essential. Maintenance inspections should be routinely scheduled, and should always include documentation with details such as inspections performed and date of inspection. Keeping records of the type of maintenance performed and the condition of equipment, including any areas of degradation such as reduced battery runtime, will help organisations to predict future failure.

Monitoring and maintenance are of the utmost importance in preventing problems before they occur, and minimising the effects of costly downtime to a business. Certain factors can easily be controlled to help extend UPS life through optimal conditions, and understanding the effects of elements like temperature and environment. Utilising a reputable brand of UPS from a reliable service provider or partner, and making use of the management features available, can help organisations to leverage their UPS investment to maximum advantage.

Cape Town not so calm – if you’re a driver

Cape Town drivers lose on average 162 hours a year to traffic jams, so will need some tech and a few tips to stay calm

Published

on

Cape Town drivers lose, on average, 162 hours a year stuck in traffic jams, and the city is ranked 95th out of around 200 cities, across 38 countries surveyed globally, in terms of congestion issues.

That’s according to the latest INRIX 2018 Global Traffic Scorecard, which is an annual analysis of mobility and congestion trends. The study provides a data-rich evaluation of information collected during peak (slowest) travel times, and inter peak (fastest point between morning and afternoon commutes) travel times. Together they provide a holistic account of congestion throughout the day, delivering in-depth insights for vehicle drivers and policy-makers to make better decisions regarding urban travel and traffic health.

Of the further five South African cities surveyed:

  • Pretoria drivers lose, on average, 143 hours a year stuck in traffic jams, ranking as the 64thmost congested city
  • Johannesburg drivers lose an average of 119 hours annually, ranking 61st
  • Durban drivers lose 72 hours, ranking 141st
  • Port Elizabeth drivers lose 71 hours, ranking 75th
  • And Bloemfontein drivers lose 62 hours, ranking 165th

If these hours sound horrific, spare a thought for the poor drivers in Colombia’s capital city of Bogotá who lose, on average, a whopping 272 hours a year stuck in traffic jams!

On average, drivers’ commutes increase by roughly 30% during peak versus inter-peak hours. And the reality is that congestion issues aren’t going away anytime soon. Not here in SA, or anywhere else in the world. So what can we, as drivers, do to make the situation easier to cope with on our daily commute?

Change of mindset

Stressing about the unavoidable, the inevitable, and all the things that are out of our control – like congestion caused by accidents, faulty street lights, or bad weather – is a waste of energy. We should try finding ways of using that time in our cars more productively, to create a less tense, more positive experience. Learning to change our perspective about this challenging time, and associating it with something enjoyable, can drastically alter our reaction to and engagement with it. Rather than expending all our energy on futile anger and frustration, we can channel our focus on things that relax or energise us instead.

Just one more chapter

Being stuck in traffic usually aggravates us because it feels like a huge waste of valuable time. But like a wise man once said, time you enjoy wasting is not wasted time. Listening to a podcast or audiobook can not only be entertaining, but also educational, which is a brilliant use of your time. Ifyou think of your car as a ‘learning lab’, a mobile university of sorts, and your time spent inside as away to exercise your brain and grow intellectually, you may even find yourself wishing for bad traffic so you have an excuse to carry on listening to your podcast or audiobook.

Tame your inner Hulk

Pulling up a playlist of your favourite, feel-good songs can do wonders to combat stress levels. Downbeat music has been proven to have a mellowing effect on drivers. Making a quick switch to downbeat music shows measurable physiological improvements, with drivers calming down much sooner, and making fewer driving mistakes. So the next time you feel your inner Hulk emerging, crank up the volume on your favourite tunes.

The power of ‘caromatherapy’

There are numerous studies on aromas and their impact on human emotion, behaviour, and performance. Researchers have found that peppermint can enhance mental and athletic performance and cognitive functioning, while cinnamon may improve tasks related to attentional processes and visual-motor response speed. A study from Kyoto University in Japan revealed that participants reported significantly lower hostility and depression scores, and felt more relaxed after awalk through a pine forest. It makes sense then, to incorporate some ‘caromatherapy’ into our lives. There are plenty of off-the-shelf car diffusers available, or you could add a few drops of essential oil to DIY felt air fresheners. Citrus scents like orange or lemon can provide a boost of energy, while rosemary can relieve stress and anxiety. Take care not to hang anything that might obstruct your field of vision though, and always make sure to test out essential oils at home first, in case a scent makes you dizzy or overly relaxed, which could affect driving focus.

Contemplate your navel

The mind is a powerful thing, and simply willing yourself to relax might be the most effective method of all. While we don’t recommend meditating while driving due to safety reasons, breathing exercises can help you stay focused and feeling calm. One useful practice is the one-to-one technique – breathing in and out for the same count with the same intensity. Deep, measured breaths facilitate full oxygen exchange, helping to slow down the rate of your heartbeat and stabilise blood pressure, as opposed to shallow breathing, which doesn’t send enough air to the lowest part of your lungs, causing you to feel anxious and short of breath. Just always keep your eyes on the road, and take care to ensure you’re not so busy counting breaths that your concentration is compromised.

Not all those who wander are lost

Some of our best ideas come in those moments where we’re alone with our own thoughts, able to really reflect on the ideas we have without having something immediate that needs our attention. Allow your mind to wander, and do a little brainstorming. Alternatively, use the time to simply day dream. Remember, downtime is not dead time. It is both necessary, and important for your mental health. Use this time as an opportunity to take care of yourself.

In-built vehicle tech

“As we spend more and more time commuting, cars are being designed to accommodate longer periods behind the wheel,” says Kuda Takura, smart mobility specialist at Ford Motor Company of Southern Africa. “Ford uses human-centric design to deliver vehicles that are inviting, accommodating, and intuitive. For example, our SYNCT infotainment system offers nifty, hands-free functions, like allowing drivers to listen to their texts, change music or climate settings, and make phone calls easily with voice control. Our range of driver-assist technologies, like Adaptive Cruise Control, Pre-Collision Assist with Pedestrian Detection and Semi-Auto Active Park Assist, are also designed to take some of the stress off city driving. If our lifestyle means that we might be spending more time in our cars than we do on holiday, then we should make sure we make the most of that time.”
