Dirty electricity is a growing issue that can be easily misunderstood due to its complexity.
To help clear up any confusion, here are some answers to common questions about dirty electricity.
What is dirty electricity?
Electricity enters homes and other buildings at a constant frequency, typically 50 or 60 hertz (Hz,) depending on which country you live in. This is considered “clean” energy as it enters your home.
The problem starts when the electricity reaches appliances, computers or other electronic devices. Many of these devices require a transformer to convert the voltage and/or current, which disrupts the flow of electricity.
These power disruptions create irregular, high frequency surges of “dirty” electricity that travel along a building’s normal wiring, which should only contain 50 or 60 Hz electricity. The surges are also known as high frequency voltage transients.
Is dirty electricity harmful to our health?
Electrical wires and any devices that use electricity emit electromagnetic fields (EMF), also known as electromagnetic radiation (EMR). These fields will easily pass through most common materials. They are strongest close to the source and diminish with distance.
