Multiple Voltage Sag Incidents in Hong Kong
Here are the details of two recent incidents:
- On April 19, 2023, power system failures in the Southern, Eastern, Wan Chai, Central, and Pok Fu Lam districts led to voltage sags, causing power outages in surrounding buildings and businesses. Within an hour, nearly a hundred incidents of people trapped and false fire alarms were reported.
- On March 17, 2023, an explosion at Fei Ngo Shan Substation caused brief voltage sags and power outages in multiple areas, with 160 elevator reports and 50 false fire alarms.
CLP's Information on Voltage Fluctuations
Electricity facilitates our daily lives. However, voltage fluctuations are inevitable in all urban power systems. Voltage fluctuations do not necessarily lead to power outages; instead, they refer to brief voltage changes. These situations can be influenced by various factors, such as tree interference, weather conditions, road construction damaging underground cables, or power facility failures. Generally, voltage fluctuations refer to voltage drops below 90% of the standard value, lasting no more than 0.1 seconds. Some household appliances may be affected, such as flickering lights or temporarily turning off and then turning back on air conditioners. Some elevators are sensitive to sudden voltage changes. When voltage fluctuations occur, operations temporarily stop, requiring professional knowledge from skilled technicians to restore normal function.
