SP Energy HubAnnual ReportReliabilitySustainabilityInnovation The Doctor Is In: Grid Health Checks Prevent Issues RELIABILITY Reading the “pulse” of network equipment, Senior Engineer Dr Lai Kai Xian can tell whether insulation material within the equipment may be breaking down. Like any good physician, Dr Lai Kai Xian is skilled in being able to look, listen and feel. The key difference is that his patient is Singapore’s electricity network, and he diagnoses the grid’s health conditions and fixes these even before they become problems. The 35-year-old electrical engineer is one of eight specialists in the SP Group’s Condition Monitoring team who keeps a close eye on the 11,000 substations and over 28,000km of cables that make up the grid. They are supported by 44 technical officers and technicians who conduct regular health screenings of all equipment on the network, and recommend deeper investigations or treatment when necessary.  Condition Monitoring Senior Engineer Dr Lai Kai Xian uses devices that require various senses – hearing, sight and touch – to assess equipment health, much like a medical doctor. Technicians take the network’s temperature using thermal guns, and listen for abnormal sounds using sensors coupled with headsets that make high frequency sounds audible. Special probes listen for the “pulse” of the equipment, and normal sounds need to be distinguished from ones that could indicate a potential problem. Sounds called transient earth voltage signals could point to internal voids in liquid, air or solid insulation material that are wrapped around cables. These kinds of “partial discharge” summon more varied equipment to pinpoint the source of an abnormality, and allow for early intervention. “These markers tell you where more investigation is needed or where problems could potentially lie so they can be solved before they get any bigger,” explains Dr Lai. He had focused his PhD studies on condition monitoring, and thanks his parents for the opportunity to have done so in Australia. SeniorEngineer Dr Lai Kai Xian (left) with his parents (right) at the 2010 University of New South Wales graduation ceremony. He was awarded a Doctor of Philosophy in Electrical Engineering. Like any emergency room, the most critical cases are attended to first, and more tests can be ordered to make a more accurate diagnosis. It can sometimes make for an intense work day, he concedes. But until his first child arrives in October, the grid is his baby – indeed his personal hobbies include reading technical articles about power systems and new technologies. Condition monitoring affords the grid an additional layer of insurance over scheduled maintenance, making it even more reliable, says Dr Lai. According to Dr Lai, an average of 70 potential problems have been avoided each year over the last five years. And unlike scheduled maintenance work which may require a piece of equipment to be taken out of service to be checked, repaired, or replaced, this pre-emptive approach is non-invasive, requiring no shutdowns. In the long run, keeping the health of a piece of equipment in check also means it lasts longer, he says. More companies are now catching on to these benefits, says Dr Lai, adding that he had trouble finding a job specifically in condition monitoring until he joined SP, a big believer in “preventive medicine”. Online monitoring is also continuously leveraged by SP for the larger 400kV and 230kV substations that make up Singapore’s transmission network, with sensors transmitting real-time data to Dr Lai’s lab. New technologies that can make the grid more robust are also regularly assessed, adds Dr Lai, also a “doctor-on-call” for casual queries from other departments, thanks to friendships forged with colleagues through weekly badminton sessions. Getting to the root of the problem is one of the things he relishes most about his role in SP’s network reliability, especially since diagnosis can be as much of an art as a science, and prompts spirited debates. “You need to be able to look beyond the obvious with data. Every single case is different, requiring both tools and thinking. That is the challenge that I love.” — 13 June 2019 TAGS PEOPLE OF SPRELIABILITY YOU MIGHT BE INTERESTED TO READ Ground feedback, digital tools: How she helps 8,000 workers end their day safely Faster repairs, fewer disruptions: Meet the innovative teams using smart tech to keep your piped gas supply flowing Engineer, 27, shares how she is undaunted by male-dominated energy industry & climbs the ranks

23 July 2014 News Release Singapore Power boosts public safety around major construction sites with two new roads for heavy vehicles Access roads at May Road and Kallang bypass schools and residential areas Singapore Power (SP) has stepped up public safety measures by building two roads for heavy construction vehicles to access its May Road and Kallang cable tunnel sites directly from expressways, bypassing nearby residential areas and schools. The move has been well received by community stakeholders, whom Singapore Power consulted in the course of undertaking this initiative. At the May Road site, SP constructed an additional lane to the Central Expressway (CTE) in the city-bound direction before the Balestier Road exit. This allows heavy vehicles to enter and exit the site without taking the narrow roads around Hong Wen School and the residential neighbourhood around McNair Road, Towner Road and May Road. At the Kallang site, an access way was created off the slip road alongside the Pan-Island Expressway (PIE), in the direction of Bendemeer at Geylang Bahru. Construction vehicles now do not drive through Geylang Bahru and Geylang Bahru Lane, as well as around Kallang Basin Swimming Complex, to enter or exit the Kallang site. The roads were built in the first half of 2014 at a total cost of about $4 million, with the one at Kallang opening first in January and the one at May Road opening in May. “At Singapore Power, we spare no effort in ensuring the safety of the community, our workers and contractors,” said Michael Chin, Managing Director (Special Projects), SP PowerGrid. “This initiative meant going beyond established industry practices for safety. We will continue to be alert to any risks and room for improvement at our sites.” The new access roads are the latest of safety measures implemented from the onset of the cable tunnel construction in end 2012. Initial safety measures included deploying traffic marshals at schools, restricting heavy vehicle traffic during school peak hours, giving talks to students to raise road safety awareness and installing water barricades to prevent jaywalking around the construction sites. SP formulated these safety measures in consultation with community stakeholders. The project teams make door-to-door visits to residents and attend monthly Residents’ Committee meetings. For the May Road site, these stakeholders included Hong Wen School, Whampoa McNair and St George’s West Residents’ Committees, Whampoa Citizens’ Consultative Committee and residents living near the site. At the Kallang site, there is regular consultation 1 with the Kallang Bahru Residents’ Committee, Kolam Ayer Citizens’ Consultative Committee, Kallang Basin Swimming Complex, Saint Joseph’s Institution Junior (when the holding school was there) and residents living near the site. “Safety is of paramount importance to us. We appreciate the continuous engagement efforts by Singapore Power, as well as the many proactive measures which it has introduced to help ensure the safety of road users in our community,” said Mr Raymond Poon, principal of Hong Wen School. “The safety of our residents and children is of the highest importance to us, so it is heartening to see the road safety measures that Singapore Power has implemented and especially the creation of this new access into the Kallang construction site,” said Chiang Heng Liang, Chairman of the Kolam Ayer Citizens’ Consultative Committee. “Prevention is better than cure, so it is prudent to segregate heavy vehicle traffic from the residential road network when and where feasible.” All heavy vehicles entering or exiting the May Road site will use the new access road, only outside of peak hours, to ensure minimal impact on CTE traffic. The existing safety measures along May Road will remain in force as light vehicles continue to use the previous site access. All vehicles entering or exiting the Kallang site will use the new access road instead of Geylang Bahru Lane.
