⚡ Power Surge Info and Tips ⚡
We’ve had a few calls lately from customers in the south east suburbs reporting power surge issues, so we thought it’d be helpful to share some info on power surges and how you can protect your appliances.
💡 What causes power surges?
- Lightning strikes and storms
- Faulty or aging wiring
- Interruptions in the power grid
⚠️ Even a quick surge lasting milliseconds can damage your TVs, computers, fridges, and other expensive electronics.
⚠️ Why Power Grid Interruptions Cause Surges in Melbourne
Maintenance and Upgrades: Power companies regularly perform maintenance and upgrades to keep the grid reliable. Sometimes switching equipment on/off or re-routing power can cause brief voltage spikes.
❗Equipment Failures: Transformers, circuit breakers, and other grid hardware can occasionally malfunction or fail, leading to sudden changes in electrical flow.
❗High Demand Periods: During hot days or peak usage times, increased electricity demand can stress the grid and cause fluctuations in voltage.
❗Wildlife and External Damage: Animals, tree branches, or vehicles damaging power lines can cause faults and interruptions.
❗Weather Effects Beyond Storms: Even outside storm season, strong winds, heat, or other weather conditions can affect power infrastructure, causing surges or outages.
Though these interruptions are usually brief, they can create power surges that harm your home electronics, which is why surge protection is a smart investment all year round.
🔌 How to protect your appliances:
✅ Unplug devices during storms or if you notice flickering power
✅ Use quality surge-protecting powerboards for individual devices
✅ Install a whole-home surge protector at your switchboard — this offers lasting protection for your home and appliances in the case of a surge
💰 Surge protectors usually cost less than a typical insurance claim for damaged electronics or appliances.
