Minor fluctuations in voltage on the system may occur during a storm or when a branch touches a wire, for example. If the problem is due to a branch, you can make a request for tree pruning online or by calling our customer services.
Voltage fluctuations may affect some of your more sensitive electronic equipment, such as CD and DVD players, televisions and computers. Plug your electronic devices into a CSA- or ULC-compliant power bar equipped with surge protection or an uninterruptible power supply. Try not to plug your devices into the same circuit as a motor-powered appliance such as a dishwasher or refrigerator.
While Hydro-Québec operates and maintains the power system to exacting standards, voltage variations cannot always be avoided. Protecting your electric and electronic devices is your responsibility.
