Surge & Brownout Protection
Power surges and brownouts are different problems that need different protection. A surge is a sudden voltage spike, often from storms or switching on the network, and it can damage TVs, computers, air conditioners and appliances in an instant. A brownout is a drop in voltage that makes motors and compressors work harder and can shorten their life. A surge diverter on its own won't stop brownouts. We check what's happening at your property and recommend the right protection for each issue, so you don't pay for the wrong fix. Energex recommends a layered approach to surge protection.
The right protection for each problem:
-
Storm and lightning surges: A surge diverter (SPD) fitted at your switchboard.
​
-
Sensitive electronics: Plug-in surge protection for TVs, computers and home offices, layered with switchboard protection.
​
-
Lights dimming, appliances struggling: Under-voltage (brownout) protection that switches off sensitive equipment when the voltage drops.
​
-
Voltage swings: Over and under-voltage protection for air conditioners, pumps, fridges and freezers.
​
-
Repeated problems: Testing your supply and switchboard to find the cause before recommending a fix.
​
-
Businesses: Protection for refrigeration, compressors and IT equipment.
