Dirty Electricity
The invisible noise in your electrical supply: what it is, where it comes from, and how to filter it out.
Clean power isn't always what comes out of the wall.
Dirty electricity refers to high-frequency voltage transients that ride on top of the standard 50Hz power supply. These aren't part of the electricity you ordered. They're introduced by the devices we now run constantly throughout our homes and workplaces.
Modern households are full of switch-mode power supplies: phone chargers, laptop adapters, LED light drivers, variable-speed appliances, and solar inverters. Each one converts power in a way that introduces high-frequency noise back into the circuit. That noise travels through your wiring and radiates from every cable in your walls.
Research into dirty electricity is ongoing, but a growing body of evidence links elevated high-frequency transients to fatigue, headaches, reduced concentration, and disrupted sleep, particularly in sensitive individuals and children.
Our Dirty Electricity Services
Dirty Electricity Assessment
We measure the high-frequency transient levels in your home using a calibrated DE meter, identifying the worst-affected circuits and sources.
Line Conditioning and Filtering
We install appropriate filters at key points in your electrical system to reduce transient levels on the circuits where you spend the most time.
Source Identification and Reduction
We identify the highest-generating devices in your home and advise on replacement or isolation strategies to reduce noise at its source.
Solar System Review
Solar inverters are one of the most significant sources of dirty electricity in modern homes. We assess your system's contribution and recommend solutions.
New Build Dirty Electricity Design
For new builds, we design the electrical system from the outset to minimise dirty electricity generation: circuit separation, quality components, and filtered sub-boards where appropriate.
